Because you don't want the Spirit inspired word, you opted to tweak the meaning. It is a childish response if not a heretical view. Common theological/ecclesiastical meaning of salvation is the saving of the soul and I agree that it is the deliverance from sin and admission to eternal bliss, wrought for man by the atonement of Christ.
Well, if one is already saved, born again and sin, the scriptures says he needs to confess it and God s faithful to forgives us. In summary, when one sinned as saved, born again accordingly, we are forgiven as a result:
Scripture: from confession
ForrestGreenCook: of believing
King James Bible
1 John 1:9 If we confess our sins, he is faithful and just to forgive us
our sins, and to cleanse us from all unrighteousness.
