If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness.
- 1 John 1:9, NIV
The blood of Jesus is sufficient for the forgiveness of any and all sins because the Cross was two thousand years ago and all of our sins were still to come. Therefore, all of our sins, whether we committed them yesterday or today or have yet to commit them tomorrow, are covered by His blood – past sins, present sins, future sins, big sins, small sins, or medium-size sins – it makes no difference.
Praise God for the blood of Jesus that is sufficient to cover all of our sins! All of them! Big sins like murder. Little sins like gossip. Medium-size sins like losing your temper. They are all under the blood of Jesus, and we are free just to enjoy our forgiveness! We will never be held accountable for the guilt of our sins because Jesus has taken the punishment for us.
