That is the voice of prayer. I come to seek God because I need Him. That is a formula for prayer. I come to adore His splendor, and fling myself and all that I have at His feet. That is the formula for worship.
Worship is all that is involved in adoration.
Worship is all the responses of the soul to the infinite soul, all the Godward activities of humankind. The descending current includes all forms of revelation, the ascending current all forms of prayer. But it can be argued that both of these are the same, that God descending action causes us to lift up our hearts in prayer to God. Thus, in a sense all worship is initiated by God. Our impulse to worship comes not from us but from God.
