Worship is not just something believers do to show devotion to God, but is where God transforms them. In worship, God recalibrates their hearts, reforms their desires, and changes their loves. Worship is the place where God trains believers' hearts. The passage encourages being strong and courageous in following God's law, not turning from it, and meditating on it day and night so that one may prosper and have success, as God will be with believers wherever they go.
