As a born again Christian we have received abundant forgiveness from the Lord of our sins. Anyone that does not know the Lord can know Him because of the grace and mercy of the Lord Jesus Christ.
Psalm 32:1-2 says: Blesses is he whose transgression is forgiven, whose sin is covered. Blessed is the man unto whom the Lord imputeth not iniquity, and in whose spirit there is no guile.
We are blessed and have abundant joy in our hearts because of the forgiveness that comes freely from the Lord. We have been forgiven for our willful disobedience and rebellion. We all have missed the mark and the Lord knows that we are imperfect. If we were still in our sin as a Christian there would be no way that we could see the Lord in heaven. Because of the forgiveness that the Lord shows toward us we have been reconciled back to God. The Lord forgives all sin no matter how big or small we think they are.
In Psalm 32:5 the Psalmists says that he acknowledged his sin before the Lord.
Psalm 32:5: I acknowledged my sin unto thee, and mine iniquities have I not hid. I said, I will confess my transgressions unto the Lord; and thou forgavest the iniquity of my sin. Selah.
