It would seem that it is, technically, a work on God's
part, rather than on man's:
Acts 5:31 God has exalted to his right hand this very man as
our Leader and Savior
in order to extend repentance and
forgiveness of sins to Israel.
Acts 11:18 When they heard this, they quieted down and
glorified God, saying, "Well then,
God has granted to the
Gentiles also the repentance that leads to life."
2 Timothy 2:24-26 The Lord's bond-servant must not be
quarrelsome, but be kind to all, able to teach, patient when
wronged, with gentleness correcting those who are in
opposition, if perhaps
God may grant them repentance
leading to the knowledge of the truth, and they may come to
their senses and escape from the snare of the devil, having
been held captive by him to do his will.
