Psalm 103:12: As far as the east is from the west, so far has he set our sins from us.
I have always love this verse because of the logic - I'm one of those people who loves things to be logical!
If we go North or South we will continue to go that direction until we reach the North or South pole, then we change direction...
But is we go East or West, we can continue going in that direction without end even though we may be covering the same ground over and over again, there is no end.
So when God said our sins would be separated as far as the East and the West, he meant a very long way! Take comfort...
