The Lord is nigh unto them that are of a broken heart; and saveth such as be of a contrite spirit. Psalm 34:18.
Do not think that because you have made mistakes you must always be under condemnation, for this is not necessary….
Shall we look at our sins, and begin to mourn, and say, I have done wrong, and I cannot come to God with any degree of confidence? Does not the Bible say, “If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness”? 1 John 1:9. It is a proper thing for us to have a realization of the terrible character of sin. It was sin that caused Christ to suffer an ignominious death on Calvary. But while we should understand that sin is a terrible thing, yet we should not listen to the voice of our adversary, who says, “You have sinned, and you have no right to claim the promises of God.” You should say to the adversary, “It is written, ‘If any man sin, we have an advocate with the father, Jesus Christ the righteous’ (1 John 2:1).” …
The psalmist says, “I acknowledged my sin unto thee, and mine iniquity have I not hid. I said, I will confess my transgressions unto the Lord; and thou forgavest the iniquity of my sin.” Psalm 32:5…. This is the kind of experience that we should have.27Letter 97, 1895.
David was pardoned of his transgression because he humbled his heart before God in repentance and contrition of soul, and believed that God’s promise to forgive would be fulfilled. He confessed his sin, repented, and was reconverted. In the rapture of the assurance of forgiveness, he exclaimed, “Blessed 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.” Psalm 32:1, 2. The blessing comes because of pardon; pardon comes through faith that the sin, confessed and repented of, is borne by the great Sin Bearer. Thus from Christ cometh all our blessings. His death is an atoning sacrifice for our sins. He is the great Medium through whom we receive the mercy and favor of God.28SDA Bible Commentary 3:1146.
