This is one of the great promises and one needed by everybody, for "all have sinned, and come short of the glory of God" (Rom. 3:32), and "the wages of sin is death" (Rom. 6:23). This is one of the absolutely necessary steps toward heaven--confession of sin. Read the connection here. It is the Lord who forgives our sins, the Lord who cleanses us from all unrighteousness. And He is faithful. He will not forget one sin; He will not overlook one. Every sin will be cleansed, every one will be forgiven. His death was an atoning sacrifice "for the sins of the whole world" (1 John 2:2).
Not only is He faithful, but He is just. If we confess our sins and accept Christ as our Redeemer, it would be unjust on God's part not to forgive us, since Jesus has died for our sins--every one of them. The debt has been canceled on the cross. It cannot be collected now.
Political offenders are sometimes given what is called an amnesty. That means, literally, a "not remembering." This is exactly what the Lord grants to everyone who comes to Him through His Son Jesus Christ. No matter what the offense or offenses may be, God, who is ready to pardon, says, "Their sins and iniquities will I remember no more" (Heb. 10:17).
Not only does our God forgive, but He cleanses from all unrighteousness. The life of the Christian is to be like His every day. Deliverance from the condemnation of sin is justification, and deliverance from the power of sin is sanctification. Someday He will deliver from the presence of sin, , and that will be glorification. Until that day let us lean upon this wonderful promise.
MEDITATION PRAYER: "Iniquities prevail against me: as for our transgressions, thou shalt purge them away" (Ps. 65:3).
