Our function is to move the body from worldly surroundings and into the midst and presence of The Holy God (Hebrews 9:1-14) through thanksgiving, praise, and worship.  We enter His gates with thanksgiving in our hearts and into His courts with praise.  Be thankful unto Him and bless His name (Psalms 100).  It is through the shed blood of Jesus that we are cleansed (I John 1:17) and gain entrance into the Holy of Holies (Hebrews 4:16) into the presence of God (the Shekinah Glory), where we commune with God, and receive from Him.  The body should then be prepared to receive declaration of the Word of God.
