Being saved does not mean merely escaping punishment but being delivered from the evil that dwells within us. It is not punishment that must be eliminated but sin, the rejection of God and of love which already bears the punishment in itself.
The Prophet Jeremiah was to say to the rebellious people: “Your wickedness will chasten you, and your apostasy will reprove you. Know and see that it is evil and bitter for you to forsake the Lord your God” (Jer 2:19).
It is from this sorrow and bitterness that the Lord wishes to save man, liberating him from sin. Therefore, however, a transformation from within is necessary, some foothold of of goodness, a beginning from which to start out in order to change evil into good, hatred into love, revenge into forgiveness..
