We want you to know, brothers and sisters, about the grace of God that was given to the churches of Macedonia: During a severe trial brought about by affliction, their abundant joy and their extreme poverty overflowed in a wealth of generosity on their part. I can testify that, according to their ability and even beyond their ability, of their own accord, they begged us earnestly for the privilege of sharing in the ministry to the saints, and not just as we had hoped. Instead, they gave themselves first to the Lord and then to us by God's will. So we urged Titus that just as he had begun, so he should also complete among you this act of grace.

Now as you excel in everything—in faith, speech, knowledge, and in all diligence, and in your love for us—excel also in this act of grace. I am not saying this as a command. Rather, by means of the diligence of others, I am testing the genuineness of your love. For you know the grace of our Lord Jesus Christ: Though he was rich, for your sake he became poor, so that by his poverty you might become rich. And in this matter I am giving advice because it is profitable for you, who began last year not only to do something but also to want to do it. Now also finish the task, so that just as there was an eager desire, there may also be a completion, according to what you have. For if the eagerness is there, the gift is acceptable according to what a person has, not according to what he does not have. It is not that there should be relief for others and hardship for you, but it is a question of equality. At the present time your surplus is available for their need, so that their abundance may in turn meet your need, in order that there may be equality. As it is written: The person who had much did not have too much, and the person who had little did not have too little.

Thanks be to God, who put the same concern for you into the heart of Titus. For he welcomed our appeal and, being very diligent, went out to you by his own choice. We have sent with him the brother who is praised among all the churches for his gospel ministry. And not only that, but he was also appointed by the churches to accompany us with this gracious gift that we are administering for the glory of the Lord himself and to show our eagerness to help. We are taking this precaution so that no one will criticize us about this large sum that we are administering. Indeed, we are giving careful thought to do what is right, not only before the Lord but also before people. We have also sent with them our brother. We have often tested him in many circumstances and found him to be diligent—and now even more diligent because of his great confidence in you. As for Titus, he is my partner and coworker for you; as for our brothers, they are the messengers of the churches, the glory of Christ. Therefore, show them proof before the churches of your love and of our boasting about you.
– 2 Corinthians 8

So then, dear friends, since we have these promises, let us cleanse ourselves from every impurity of the flesh and spirit, bringing holiness to completion in the fear of God.

Make room for us in your hearts. We have wronged no one, corrupted no one, taken advantage of no one. I don't say this to condemn you, since I have already said that you are in our hearts, to die together and to live together. I am very frank with you; I have great pride in you. I am filled with encouragement; I am overflowing with joy in all our afflictions.

In fact, when we came into Macedonia, we had no rest. Instead, we were troubled in every way: conflicts on the outside, fears within. But God, who comforts the downcast, comforted us by the arrival of Titus, and not only by his arrival but also by the comfort he received from you. He told us about your deep longing, your sorrow, and your zeal for me, so that I rejoiced even more. For even if I grieved you with my letter, I don't regret it. And if I regretted it—since I saw that the letter grieved you, yet only for a while— I now rejoice, not because you were grieved, but because your grief led to repentance. For you were grieved as God willed, so that you didn't experience any loss from us. For godly grief produces a repentance that leads to salvation without regret, but worldly grief produces death. For consider how much diligence this very thing—this grieving as God wills—has produced in you: what a desire to clear yourselves, what indignation, what fear, what deep longing, what zeal, what justice! In every way you showed yourselves to be pure in this matter. So even though I wrote to you, it was not because of the one who did wrong, or because of the one who was wronged, but in order that your devotion to us might be made plain to you in the sight of God. For this reason we have been comforted.

In addition to our own comfort, we rejoiced even more over the joy Titus had, because his spirit was refreshed by all of you. For if I have made any boast to him about you, I have not been disappointed; but as I have spoken everything to you in truth, so our boasting to Titus has also turned out to be the truth. And his affection toward you is even greater as he remembers the obedience of all of you, and how you received him with fear and trembling. I rejoice that I have complete confidence in you.
– 2 Corinthians 7:1-13

We are not giving anyone an occasion for offense, so that the ministry will not be blamed. Instead, as God’s ministers, we commend ourselves in everything: by great endurance, by afflictions, by hardships, by difficulties, by beatings, by imprisonments, by riots, by labors, by sleepless nights, by times of hunger, by purity, by knowledge, by patience, by kindness, by the Holy Spirit, by sincere love, by the word of truth, by the power of God; through weapons of righteousness for the right hand and the left, through glory and dishonor, through slander and good report; regarded as deceivers, yet true; as unknown, yet recognized; as dying, yet see—we live; as being disciplined, yet not killed; as grieving, yet always rejoicing; as poor, yet enriching many; as having nothing, yet possessing everything. We have spoken openly to you, Corinthians; our heart has been opened wide. We are not withholding our affection from you, but you are withholding yours from us. I speak as to my children; as a proper response, open your heart to us.

Do not be yoked together with those who do not believe. For what partnership is there between righteousness and lawlessness? Or what fellowship does light have with darkness? What agreement does Christ have with Belial? Or what does a believer have in common with an unbeliever? And what agreement does the temple of God have with idols? For we are the temple of the living God, as God said:

I will dwell
and walk among them,
and I will be their God,
and they will be my people.

Therefore, come out from among them
and be separate, says the Lord;
do not touch any unclean thing,
and I will welcome you.

And I will be a Father to you,
and you will be sons and daughters to me,
says the Lord Almighty.

– 2 Corinthians 6:3-18

From now on, then, we do not know anyone from a worldly perspective. Even if we have known Christ from a worldly perspective, yet now we no longer know him in this way. Therefore, if anyone is in Christ, he is a new creation; the old has passed away, and see, the new has come!

Everything is from God, who has reconciled us to himself through Christ and has given us the ministry of reconciliation. That is, in Christ, God was reconciling the world to himself, not counting their trespasses against them, and he has committed the message of reconciliation to us.

Therefore, we are ambassadors for Christ, since God is making his appeal through us. We plead on Christ's behalf, "Be reconciled to God." He made the one who did not know sin to be sin for us, so that in him we might become the righteousness of God.

Working together with him, we also appeal to you, "Don't receive the grace of God in vain." For he says: At an acceptable time I listened to you, and in the day of salvation I helped you. See, now is the acceptable time; now is the day of salvation!

– 2 Corinthians 5:16-6:2

For we know that if our earthly tent we live in is destroyed, we have a building from God, an eternal dwelling in the heavens, not made with hands. Indeed, we groan in this tent, desiring to put on our heavenly dwelling, since, when we are clothed, we will not be found naked. Indeed, we groan while we are in this tent, burdened as we are, because we do not want to be unclothed but clothed, so that mortality may be swallowed up by life. Now the one who prepared us for this very purpose is God, who gave us the Spirit as a down payment.

So we are always confident and know that while we are at home in the body we are away from the Lord. For we walk by faith, not by sight. In fact, we are confident, and we would prefer to be away from the body and at home with the Lord. Therefore, whether we are at home or away, we make it our aim to be pleasing to him. For we must all appear before the judgment seat of Christ, so that each may be repaid for what he has done in the body, whether good or evil.

Therefore, since we know the fear of the Lord, we try to persuade people. What we are is plain to God, and I hope it is also plain to your consciences. We are not commending ourselves to you again, but giving you an opportunity to be proud of us, so that you may have a reply for those who take pride in outward appearance rather than in the heart. For if we are out of our mind, it is for God; if we are in our right mind, it is for you. For the love of Christ compels us, since we have reached this conclusion, that one died for all, and therefore all died. And he died for all so that those who live should no longer live for themselves, but for the one who died for them and was raised.

– 2 Corinthians 5:1-15

Now we have this treasure in clay jars, so that this extraordinary power may be from God and not from us. We are afflicted in every way but not crushed; we are perplexed but not in despair; we are persecuted but not abandoned; we are struck down but not destroyed. We always carry the death of Jesus in our body, so that the life of Jesus may also be displayed in our body. For we who live are always being given over to death for Jesus's sake, so that Jesus's life may also be displayed in our mortal flesh. So then, death is at work in us, but life in you. And since we have the same spirit of faith in keeping with what is written, I believed, therefore I spoke, we also believe, and therefore speak. For we know that the one who raised the Lord Jesus will also raise us with Jesus and present us with you. Indeed, everything is for your benefit so that, as grace extends through more and more people, it may cause thanksgiving to increase to the glory of God.

Therefore we do not give up. Even though our outer person is being destroyed, our inner person is being renewed day by day. For our momentary light affliction is producing for us an absolutely incomparable eternal weight of glory. So we do not focus on what is seen, but on what is unseen. For what is seen is temporary, but what is unseen is eternal.

2 Corinthians 4:7-18

Therefore, since we have this ministry because we were shown mercy, we do not give up. Instead, we have renounced secret and shameful things, not acting deceitfully or distorting the word of God, but commending ourselves before God to everyone's conscience by an open display of the truth.

But if our gospel is veiled, it is veiled to those who are perishing. In their case, the god of this age has blinded the minds of the unbelievers to keep them from seeing the light of the gospel of the glory of Christ, who is the image of God.

For we are not proclaiming ourselves but Jesus Christ as Lord, and ourselves as your servants for Jesus's sake. For God who said, "Let light shine out of darkness," has shone in our hearts to give the light of the knowledge of God's glory in the face of Jesus Christ.
– 2 Corinthians 4:1-6

Such is the confidence we have through Christ before God. It is not that we are competent in ourselves to claim anything as coming from ourselves, but our adequacy is from God. He has made us competent to be ministers of a new covenant, not of the letter, but of the Spirit. For the letter kills, but the Spirit gives life.

Now if the ministry that brought death, chiseled in letters on stones, came with glory, so that the Israelites were not able to gaze steadily at Moses’s face because of its glory, which was set aside, how will the ministry of the Spirit not be more glorious? For if the ministry that brought condemnation had glory, the ministry that brings righteousness overflows with even more glory. In fact, what had been glorious is not glorious now by comparison because of the glory that surpasses it. For if what was set aside was glorious, what endures will be even more glorious.

Since, then, we have such a hope, we act with great boldness. We are not like Moses, who used to put a veil over his face to prevent the Israelites from gazing steadily until the end of the glory of what was being set aside, but their minds were hardened. For to this day, at the reading of the old covenant, the same veil remains; it is not lifted, because it is set aside only in Christ. Yet still today, whenever Moses is read, a veil lies over their hearts, but whenever a person turns to the Lord, the veil is removed. Now the Lord is the Spirit, and where the Spirit of the Lord is, there is freedom. We all, with unveiled faces, are looking as in a mirror at the glory of the Lord and are being transformed into the same image from glory to glory; this is from the Lord who is the Spirit.
