2 Corinthians 1:17-20

Yea, yea, and nay, nay?— The sense of these verses is, "I did not change my design through levity, nor did I purpose first one thing and then the contrary, as selfish views might determine me, 2 Corinthians 1:18. As God is true, we have never prevaricated with you, 2 Corinthians 1:19. For what I, Sylvanus, and Timothy have preached concerning Jesus Christ the Son of God, is not inconsistent, but invariably the same, 2 Corinthians 1:20. For all the promises of God are ratified in and verified by him to the glory of God by our preaching." And besides, in Christ there is such a real evidence of God's conversing with men; and such wonders actually wrought, in the incarnation, life, death, resurrection, and ascension of his Son, (facts in themselves much more wonderful than any of the glorious consequences to follow,) as tend greatly to confirm our faith, and make it easier for us to believe such illustrious promises as those which are given us, the very greatness of which might otherwise have been an impediment to our faith, and have created a suspicion, not whether God would have performed what he had promised, but whether such promises were really given us: and we may add, that God could not have given such promises, except in and through Christ, unless he were unjust, which is impossible.
