The Son of God, Christ Jesus, proclaimed among you by us . . . was never a blend of Yes and No. With him it was, and is, Yes.
He is the Yes pronounced upon God's promises, every one of them.
That is why, when we give glory to God, it is through Christ Jesus that we say "Amen." And if you and we belong to Christ, guaranteed as his and anointed, it is all God's doing; it is God also who has set his seal upon us, and as a pledge of what is to come has given the Spirit to dwell in our hearts.
Second Corinthians 1
