Passage
For all the promises of God in him are yea, and in him Amen, unto the glory of God by us.
For all the promises of God in him are yea, and in him Amen, unto the glory of God by us.
2 Corinthians 1:18 But as God is true, our word toward you was not yea and nay.
2 Corinthians 1:19 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.
2 Corinthians 1:20 For all the promises of God in him are yea, and in him Amen, unto the glory of God by us.
2 Corinthians 1:21 Now he which stablisheth us with you in Christ, and hath anointed us, is God;
2 Corinthians 1:22 Who hath also sealed us, and given the earnest of the Spirit in our hearts.
The verse centers on "promises", "amen", and "glory". It is saying that the verse draws attention to "promises" and "amen", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 19's "For the Son of God Jesus Christ..." into verse 21's "Now he which stablisheth us with you...", so "promises" and "amen" belong inside that flow. In 2 Corinthians context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "promises" and "amen" with trust shaped by these words, not by a vague optimism outside the passage.
