Arguably the greatest calling in life is the call to worship. The Lord is In His holy temple, let all the earth keep silence. This is the day that the Lord has made, I will rejoice and be glad in it. Oh taste and see that the Lord is good. Enter into His gates with thanksgiving and His courts with praise. During this time the worship leader gives the worshippers a call or invitation to worship God. Some need a reason to worship, others need a reminder to worship, but all true worshippers are required to worship in Spirit and in Truth.
