Isaiah 43:25 I, even I, am He who blots out your transgressions for My own sake; And I will not remember your sins.
Why have the previous verse after the last verse? Because we have to remember why God has done what He has for each of us.
He does not do this to make us happy to be alive; He does this for His own sake, so we can glorify Him with our lives.
He is the One who will forgive us when we bring our sins to Him. He has already promised to do this. But He does this so we can continue to bring Him the glory and not the other way round.
Yes, He loves us more than we can imagine; but He is still God Almighty!
