But there are times when God makes Himself so known that the only way I can express worship in that moment is to simply to be quiet. We are to fear God. Psalm 62, My soul waits in silence for God only. Worship is being overcome by the presence of God and the language of response is speechlessness. The second word here is to give Him glory.
Worship is awe, but worship is also allegiance.
We are to give Him glory. We are to come before Him with respect. God is majestic. Because he is the king, we are to give Him glory. You and it is an unbridled expression of allegiance to Christ.
