2 Corinthians 1:18-20

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