Dear friend the main purpose of worship is to glorify, honor, exalt and praise God Almighty.
When we worship God Almighty it is a time we pay deep, true respect and love to our creator.
John 4:23-24
But the hour cometh, and now is, when the true worshippers shall worship the Father in spirit and in truth: for the Father seeketh such to worship him.
God is a Spirit: and they that worship him must worship him in spirit and in truth.
Psalms 86:9-10
All nations whom thou hast made shall come and worship before thee, O Lord; and shall glorify thy name.
For thou art great, and doest wondrous things: thou art God alone.
