God Is Faithful

The rainbow is a promise.

1 Corinthians 1:9

King James Version (KJV)

⁹ God is faithful, by whom ye were called unto the fellowship of his Son Jesus Christ our Lord.

^{The Message Bible I Corinthians 1:7 through 9
7-9} Just think—you don’t need a thing, you’ve got it all! All God’s gifts are right in front of you as you wait expectantly for our Master Jesus to arrive on the scene for the Finale. And not only that, but God himself is right alongside to keep you steady and on track until things are all wrapped up by Jesus. God, who got you started in this spiritual adventure, shares with us the life of his Son and our Master Jesus. He will never give up on you. Never forget that.

This is the entire First Epistle of St.Paul to the Corinthians, read by Alexander Scourby.  'God is faithful' is one of the main themes.
