2 Corinthians 1:17-20

17You may be asking why I changed my plan. Do you think I make my plans carelessly? Do you think I am like people of the world who say “Yes” when they really mean “No”?

18As surely as God is faithful, our word to you does not waver between “Yes” and “No.”

19For Jesus Christ, the Son of God, does not waver between “Yes” and “No.” He is the one whom Silas, Timothy, and I preached to you, and as God’s ultimate “Yes,” he always does what he says.

20For all of God’s promises have been fulfilled in Christ with a resounding “Yes!” And through Christ, our “Amen” (which means “Yes”) ascends to God for his glory.
