Psalm 105:8 He hath remembered his covenant for ever, The word which he commanded to a thousand generations.
This is one of the most comforting truths in the Bible. God remembers what He says. God keeps His Word. I can often tell someone something and forget that I said it. I can make promises and forget them. It seems easy to say and not do. That is wrong of me but it is the truth that I have suffered from this weakness.
God never forgets. He remembers. He keeps His Word. There is no end to when or how He will forget. He will remember. He made promises to Israel that didn’t come true for hundreds of years but they always do come true.
He made us promises of salvation. He made us promises about His character. He will never tell us, I said it but I didn’t mean it. He will never say I said it but I forgot I said it.
That is not going to happen. He is God and He is good. He is God and He keeps His Word.
