What does it mean to render to God what is His?

To render to God what is His means recognizing all that we owe to Him, which includes perfect obedience, love, and worship. As believers, we acknowledge that God deserves our unreserved devotion, which is exemplified by the Lord Jesus Christ who rendered perfect obedience to the Father. We cannot achieve this perfection ourselves, but through faith in Christ, we strive to give God our best—our trust, our gratitude, and our worship. This involves actively living out our faith in all areas of life and coming before Him with thankful hearts, acknowledging His goodness and grace.
