103. As there is in man, from the Lord, this ability to reciprocate and return, and consequently this mutuality, the Lord says that a man must do the work of repentance, which no one can do except as of himself:
Jesus said: Except ye repent ye shall all perish (Luke 13:3, 5).
Jesus said: The kingdom of God is at hand; repent ye, and believe the gospel (Mark 1:14-15).
Jesus said: I am come to call sinners to repentance (Luke 5:32).
Jesus said to the churches: Repent (Rev. 2:5, 16, 21-22; 3:3).
It is also said:
They repented not of their works (Rev. 16:11).
