How do we live in God’s power rather than our own? This concept seems to mean different things to different people.
It seems like for some people this means a “let go and let God” model of discipleship to tap in to God’s power. To others it assumes God’s abiding power in the Christian life and our personal effort is exerted.
How can we practically operate in God’s power rather than our own?
Brother, I would commend to you Walter Marshall's
The Gospel Mystery of Sanctification, wherein he discusses what it is to "live in God's power" by faith, and demystifies -in my estimation- the concept. One consideration is that we begin our day acknowledging that we have no help if God is not our help, and that we cry to Him that if it is not
He who turns us, we will not be turned.
Living in God's power begins with truly -by faith- believing those practical and unequivocal promises that He
will give us every good gift, and not like our earthly fathers, but as a perfect heavenly father. These good gifts include:
1. Progress in mortification
2. Progress in understanding the Scripture
3. Afflictions to rid us of every vestige of self-righteousness, drive us ever to Christ, apprise us of sins, perhaps, we did not know exist,
etc.
4. Progress in listening to the Word preached, our behavior, comprehension, and gratitude at the administration of the sacrament of the Lord's Supper
5. Many, many, more.
But all of these must carried out
by faith, believing that it is the goodness of God that is the foundation for such things. In this way, then, we spend our best efforts in seeking God's commandments, by use of lawful and appointed means, but never
trusting in those means, only trusting in the God Who makes those means effectual as He sees fit, in His due time, at His good pleasure.
We do these things in the "power of God," not by some mystical
Let Go and let God empty vain practice, but as attendant children, humble, earnest, and believing. I cannot recommend Mr. Marshall's book enough, and also this sermon from the afternoon service this past Lord's Day.
