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.
Sometimes the Holy Spirit has to work with us and show us our need to confess our sin to the Lord or to forgive someone or even to forgive ourselves. We must not try and hide our sins from the Lord or harbor unforgiveness the Lord sees all and is waiting for us to come to Him and acknowledge this fact. When we do the right thing before the Lord then He can begin to restore our personal lives, and for those that are near and dear to us. This type of work of the Holy Spirit is constant in our lives and not just at the time of conversion. We must always walk in a spirit of forgiveness towards ourselves and others.
We can be deceived by our own sins for a long time. That is why we need the Power of the Holy Spirit to open our eyes as Christians. Unbelievers cannot see their need for Jesus until they are drawn by the Holy Spirit to acknowledge their need.
Acts 26:18: To open their eyes, and to turn them from darkness to light, and from the power of Satan unto God, that they may receive forgiveness of sins, and inheritance among them which are sanctified by faith that is in me.
Our eyes must be open to see what we need to hear and our ears opened to hear what we need to hear by the Power of the Holy Spirit.
