Jesus redeemed the faithful in Him from sin and commands “sin no more” – why do we continue to sin subsequent to redemption? (John 8:11)
God the Father has “justified” you and cast your sins into the sea of forgetfulness because you have trusted-believed in Jesus as Lord and entered into covenant relationship with the Father having received the Holy Spirit as Guarantor of that relationship (Ephesians 1:13-14); therefore, though you remain in a sinful body of flesh and you do, as a Christian, fall short of God’s perfection and will continue to do so from time to time in word, thought or deed (Romans 7:14-25), God has chosen by covenant promise to NOT see your sin as God only sees the righteousness of His dear Son imputed into your life (2 Corinthians 5:21) and God has declared you “not guilty.”
Though you have entered into covenant relationship with God the Father by faith in Jesus as Lord, you remain encumbered by a body of decay, a body of death possessing a sin-nature inherited from your father, Adam (Romans 5:12), and you’ll struggle with this sin-nature until you exhale your last breath but if you are faithful and walk by the indwelling Holy Spirit given you for sanctification, you will not repeatedly compromise with the flesh, with the World, with the Devil, but you will incrementally grow stronger in the Lord through obedience to the Spirit (Galatians 5:16) as you walk in intimate fellowship with Jesus, daily. You are forgiven by grace through faith; therefore, walk in peace and love and fellowship in the Holy Spirit (Romans 5:1) in the knowledge that no one, nothing, will snatch you out of the hand of our God (John 10:28-30).
In closing…a brief caveat…grace is NOT a license to sin and the one who professes Jesus as Lord and continues to live in wilful sin void conscience has every reason to question the validity of their faith and relationship with God (Matthew 7:15-20).
