Do it

Salvation is by faith through grace and so is sanctification. We cannot in and of ourselves do what God wants us to do. But yet he tells us to do things. To be kind, to forgive, to do all without complaining or arguing, to be humble, to love (and what a love). He expects us to do them, yet rely on Him for that ability. Hard to wrap your mind around. I think the thing is not so much to waste time trying to understand it all, though certainly immersing yourself in God's Word and absorbing more and more of the heart of God is never a waste of time, but to do it. Just do it. Easier to steer what's already moving and all that.
Grace will find you.
