"We believe that all who are justified will win the fight of faith. They will persevere in faith and will not surrender finally to the enemy of their souls. (...) No amount of willpower, determination, or resolve can even exist unless God acts first and continues to act in the human heart. True faith is a gift from God. (...) God’s preserving work compels us to become active participants with wartime mentalities against indwelling sin. (...) True faith makes us fighters, and in Christ we are more than conquerors; we’re heirs with him (, )."
