text: why do christians always sing in church? has this always been the case?  is it a form of entertainment? should n't you be able to praise god without music? it is proper that music be one means by which the church expresses her unity. singing is an act which unites god's people at all times in history, on heaven and earth in the common praise of god.    "behold, how good and how pleasant it is for brethren to dwell together in unity!" psalm 133:1  singing is to be an outward manifestation of ones faith and joy. it is in response to god's saving work and finds expression not in unhindered self-expression, but in humble, disciplined participation in the body of christ.  by singing, we are reminded (and remind others) of the reality of the church's unity in christ, her presence on heaven and earth, of our individual contribution as a member of the body, and, preeminently, of our great god who is the subject of our praise.
