Notice that - If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness (vs. 9) is
IN CONTRAST TO - If we
say that we
have no sin, (present tense) we
deceive ourselves, and
the truth is not in us (vs. 8) and - If we
say that we
have not sinned, (past tense) we
make him a liar, and
his word is not in us (vs. 10). Believers speak the same/acknowledge/agree with God's perspective about their sins and have a settled recognition and ongoing acknowledgment that one is a sinner in need of cleansing and forgiveness.
Although believers can repent about other specific things, to repent and believe the gospel unto salvation is not a repeated act. Jesus is the door. (John 10:9) He is not a revolving door.
Chapter and verse please. Do you disagree with
sealed until the redemption of the purchased possession/unto the day of redemption? (Ephesians 1:13-14; 4:30)
