Now that's a long way - from sun rising to sun setting, that's how far God has removed our sins. But the key word is removed. When we sin and come to God in repentance, God doesn't just forgive our sin; he purifies us of all unrighteousness. What was unholy in me is made righteous in him. What was impure is now clean. What was stained is spotless. Why? How? We can now see more fully what the Psalmist could know only in part. God doesn't see our sin, but Jesus' sacrifice. His blood purifies and cleanses us! Our sin is gone and we are clean.
