'Promise' in the Bible

And they promise them freedom, although they are themselves the slaves of what is corrupt. For a man is the slave of any one by whom he has been worsted in fight.

The Lord is not slow in fulfilling His promise, in the sense in which some men speak of slowness. But He bears patiently with you, His desire being that no one should perish but that all should come to repentance.

But in accordance with His promise we are expecting new heavens and a new earth, in which righteousness will dwell.
