12 For our boast is this, the testimony of our conscience, that we behaved in the world with simplicity[1] and godly sincerity, not by earthly wisdom but by the grace of God, and supremely so toward you. 13 For we are not writing to you anything other than what you read and acknowledge[2] and I hope you will fully acknowledge-- 14 just as you did partially acknowledge us--that on the day of our Lord Jesus you will boast of us as we will boast of you.
15 Because I was sure of this, I wanted to come to you first, so that you might have a second experience of grace. 16 I wanted to visit you on my way to Macedonia, and to come back to you from Macedonia and have you send me on my way to Judea. 17 Was I vacillating when I wanted to do this? Do I make my plans according to the flesh, ready to say "Yes, yes" and "No, no" at the same time? 18 As surely as God is faithful, our word to you has not been Yes and No. 19 For the Son of God, Jesus Christ, whom we proclaimed among you, Silvanus and Timothy and I, was not Yes and No, but in him it is always Yes. 20 For all the promises of God find their Yes in him. That is why it is through him that we utter our Amen to God for his glory. 21 And it is God who establishes us with you in Christ, and has anointed us, 22 and who has also put his seal on us and given us his Spirit in our hearts as a guarantee.[3]

Commentary on 2 Corinthians 1:12-14
(Read 2 Corinthians 1:12-14)
Though, as a sinner, the apostle could only rejoice and glory in Christ Jesus, yet, as a believer, he might rejoice and glory in being really what he professed. Conscience witnesses concerning the steady course and tenor of the life. Thereby we may judge ourselves, and not by this or by that single act. Our conversation will be well ordered, when we live and act under such a gracious principle in the heart. Having this, we may leave our characters in the Lord's hands, but using proper means to clear them, when the credit of the gospel, or our usefulness, calls for it.
Commentary on 2 Corinthians 1:15-24
(Read 2 Corinthians 1:15-24)
The apostle clears himself from the charge of levity and inconstancy, in not coming to Corinth. Good men should be careful to keep the reputation of sincerity and constancy; they should not resolve, but on careful thought; and they will not change unless for weighty reasons. Nothing can render God's promises more certain: his giving them through Christ, assures us they are his promises; as the wonders God wrought in the life, resurrection, and ascension of his Son, confirm faith. The Holy Spirit makes Christians firm in the faith of the gospel: the quickening of the Spirit is an earnest of everlasting life; and the comforts of the Spirit are an earnest of everlasting joy. The apostle desired to spare the blame he feared would be unavoidable, if he had gone to Corinth before he learned what effect his former letter produced. Our strength and ability are owing to faith; and our comfort and joy must flow from faith. The holy tempers and gracious fruits which attend faith, secure from delusion in so important a matter.
