The Importance of Corporate Worship

We have been redeemed from the slave market of sin to be a community that worships our God in spirit and in truth. This corporate worship includes both a giving unto the Lord as well as a receiving from Him. Do you approach His glorious presence with an open heart and an obedient ear? The outline of the sermon is as follows:
I-Let us worship our God with our whole being
II-Let us not harden our hearts but listen and obey
III-Let us labor to enter into His rest
