The Christian is “born of God”. He or she has the divine nature within. It’s impossible for the divine nature to disobey God.
1 John 5:4 For whatsoever is born of God overcometh the world: and this is the victory that overcometh the world, even our faith.
If the old nature is in control of us, we disobey God, but if the new nature is in control, we obey God.
Our victory is a result of faith in God. We grow in faith as we grow in love. The more our love for Christ is perfected, the more our faith in Christ is perfected too, because faith and love mature together.
