Worship is much more than just singing songs. In fact, true worship is first and foremost a condition of heart and a state of mind. We can be worshipping passionately without singing a single note. Worship is born in our hearts; it fills our thoughts and then it is expressed through our mouths and through our bodies. If our hearts are filled with awe for God, we may want to sing, dance, clap, or lift up our hands in worship. We may also be reverently silent and still before God. We may desire to give offerings or offer other forms of outward expression of love for God. But any of these actions done without a right heart are simply formalism and meaningless to God.
