Ephesians 6:10 Meaning Finally

Strength here is not something a person grinds out by clenched willpower. Willpower strains, tires, and finally snaps under its own effort. The strength Paul points to is drawn from a power already at work, a settled sense of who one is that steadies the whole system from underneath. A man leaning on that inner ground stops manufacturing courage by force and starts drawing it, the way a swimmer stops thrashing and lets the water hold him.

When someone quits trying to be strong and instead trusts the greater power he belongs to, the tightness in him loosens. His hands steady. The might was never his to squeeze out of himself. It was the field he stood in, and standing there, he grows quietly strong.
