Every believer in Christ can be absolutely certain of the forgiveness of his sins before God, because
- God’s promises are firm and sure.
- God has confirmed the forgiveness with an oath.
Ezek. 33:11: As I live, saith the Lord God, I have no pleasure in the death of the wicked, but that the wicked turn from his way and live.
- The Holy Spirit has sealed the forgiveness in the hearts of believers with the Word and the Sacraments.
2 Cor. 1:21-22: Now he which establisheth us with you in Christ, and hath anointed us, is God; Who hath also sealed us, and given the earnest of the Spirit in our hearts.
Rom. 4:11: Abraham received the sign of circumcision, a seal of the righteousness of the faith which he had yet being uncircumcised, that he might be the father of all them that believe, though they be not circumcised, that righteousness might be imputed unto them also.
2 Cor. 1:20: For all the promises of God in him are yea.
Heb. 6:18: It was impossible for God to lie.
Tit. 1:2: God, that cannot lie.
2 Tim. 1:12: I know whom I have believed, and am persuaded that he is able to keep that which I have committed unto him against that day.
1 Tim. 1:15: This is a faithful saying and worthy of all acceptation, that Christ Jesus came into the world to save sinners, of whom I am chief.
Thus we can be certain “that neither death, nor life, nor angels or prinicipalities, nor powers, nor things present, nor things to come, nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord. (Rom. 8:38,39)
