The Liturugy is what GOD does for us not we what we can do for GOD and that is what is missing in Evangical churches as they think worship is more of an act they do than what GOD does. From the Invocation, a reminder what GOD has done for us in baptism, to reading of scriputres and sermons which tells us what GOD does for by showing us the law and need a savior through the Gospel to communion,giving us body and blood through bread and wine.
Genesis 2:2 By the seventh day God had finished the work he had been doing; so on the seventh day he rested from all his work.
Hebrews 4:4" For somewhere he has spoken about the seventh day in these words: "And on the seventh day God rested from all his work."
Hebrews 4:9 "There remains, then, a Sabbath-rest for the people of God;"
Hebrews 4:10 "for anyone who enters God's rest also rests from his own work, just as God did from His".
