15 And being certain of this, it was my purpose to come to you before, so that you might have a second grace; 16 And by way of Corinth to go into Macedonia, and from there to come back again to you, so that you might send me on my way to Judaea. 17 If then I had such a purpose, did I seem to be changing suddenly? or am I guided in my purposes by the flesh, saying, Yes, today, and, No, tomorrow? 18 As God is true, our word to you is not Yes and No. 19 For the Son of God, Jesus Christ, whom we were preaching among you, even I and Silvanus and Timothy, was not Yes and No, but in him is Yes.
Matthew Henry's Commentary on 2 Corinthians 1:15-19
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.
