Charles Spurgeon Commentary 2 Corinthians 1:18-20

"But as God is faithful, our word toward you is not yea and nay. For the Son of God, Jesus Christ, who was preached among you by us, [even] by me and Silvanus and Timothy, was not yea and nay, but in him is yea. For how many soever be the promises of God, in him is the yea: wherefore also through him is the Amen, unto the glory of God through us." — 2 Corinthians 1:18-20 (ASV)

But as God is true, our word toward you was not yea and nay. For the Son of God, Jesus Christ, who was preached among you by us, even by me and Silvanus and Timotheus, was not yea and nay, but in him was yea. For all the promises of God in him are yea, and in him Amen, unto the glory of God by us.

Paul loved to turn from some lower subject to his Lord. When he wrote the words, "yea and nay," they suggested to him the perfect constancy of Christ's love and thankfulness for His faithful promises; so, as the thought came into his mind, he could not help but include it in the Epistle he was writing, for he never missed an opportunity of praising the Lord Jesus Christ. I wish we could all imitate him, in this respect, far more than we have ever done; for our Saviour is worthy of all the praise we can ever give him, and more, too.
