"Except ye repent, ye shall all likewise perish." Luke 13:5
The truth here asserted, is one of the foundations of Christianity. "All have sinned and come short of the glory of God." (Rom 3:23) All of us are born in sin. We are fond of sin, and are naturally unfit for friendship with God. Two things are absolutely necessary to the salvation of every one of us. We must repent, and we must believe the Gospel. Without repentance towards God, and faith towards our Lord Jesus Christ, no one can be saved.
