The simple process of coming to God is the process not only of salvation, but of joining God in his mission to reconcile the lost world. Worship is the acknowledgment of joining, sharing, mutuality. Worship is submission, but God has far more in store for our lives than simply to do something for him. He wants us to experience an intimate love relationship with him that is both real and personal. Worship is the acknowledgment of this relationship.
Worship depends upon relationship.
The heart of eternal life and the heart of Christianity is to know God and to know Jesus Christ whom he has sent. This knowledge of God, relationship with God, is not a program, study, or method. We are proclaiming in worship that God's love for us generates our love for him. I love you, Lord. The vertical aspect of worship enables the horizontal.
