The SinNature that we were born with resists moderation tending toward excess and immorality 2Ti 3:6.
The SinNature is controlled by the lust of the flesh, the lust of the eye and the pride of life. 1Jn 2:16
By the power, teaching and leading of the HolySpirit a believer is able to overcome the short-sighted, destructive urgings of the flesh. Rom 6:12
Such SelfControl is a testimony to the work of Christ in us.
