Serving the Lord.
Everything you do in the Christian life should be consistent with God’s Word and truly in His service and to His glory. In Romans 12:11, the word Paul used to describe Christian service refers to the service of a bond–slave, whose sole duty was to carry out his master’s will. That is how you ought to serve God—as a bond servant of Jesus Christ.
But you can’t serve the Lord in your own power any more than you could come to Him by your own power or will. The power to serve Christ comes from God. “To this end I also labor,” Paul testified, “striving according to His working which works in me mightily” (Col. 1:29).
