2 Corinthians 1:21-24
21 Now he which stablisheth us with you in Christ, and hath anointed us, is God;
22 Who hath also sealed us, and given the earnest of the Spirit in our hearts.
23 Moreover I call God for a record upon my soul, that to spare you I came not as yet unto Corinth.
24 Not for that we have dominion over your faith, but are helpers of your joy: for by faith ye stand.
