Willpower or self-control?

“Willpower is a secular version of self-control. Self-control is a fruit of the Spirit for management of self in the strength of Christ. Willpower is seated in the natural man, while self-control is rooted in the Vine and is a product of abiding in it. It enables the believer to wage war against the deeds of the flesh.”— Vine Ripened Life

I like that; "rooted in the Vine and is a product of abiding in it." Of course, that means if we stop abiding, the self-control stops flowing. Only as we abide can the life-giving flow of the Holy Spirit sap keep us in self-control.
