All will need the powerful inspiration of the Spirit to give them wisdom, the love fruit of the Spirit, prayer according to the mind of God, the ability to understand the Bible and let it speak to us. God gives us all this and much more without demanding the entrance fee of feeling bad about our sins. They did, but repentance need not mean any more than simply turning to God. It is after we have turned to God's satellite that we discover hilariously that we are loved and totally accepted just as we are. In due course we are astonished when others say we are beginning to change.
Heresy occurs when a truth is put in the wrong place.
The truth in the wrong place is that there is a common experience of contrition or deep conviction of sin. It comes after we have tried valiantly to love God and love our neighbour. David had already been inspired to write psalms and do exploits by the Spirit when he wrote his penitential Psalm 51 . For I do not do what I want, but I do the very thing I hate. . . Penitential conviction of sin will often grip us long after we first tuned in to God's satellite.
