God Works In Us
It happens best when we are filled with (yielded to) the Holy Spirit.
Ephesians 5:18: And be not drunk with wine, wherein is excess; but be filled with the Spirit;
Philippians 2:12-13: Wherefore, my beloved, as ye have always obeyed, not as in my presence only, but now much more in my absence, work out your own salvation with fear and trembling. 13 For it is God which worketh in you both to will and to do of his good pleasure.
F. B. Meyer:
What a staggering weight of thought is excited by these words! Stay, my soul, and wonder that the eternal God should stoop to work within thy narrow limits. Is it not a marvel indeed, that He, whom the heavens cannot contain, and in whose sight they are not clean, should trouble Himself to work on such material, so unpromising, and amid circumstances so uncongenial?
