Missions Exists Because Worship Doesn't

In light of missionary Charles Woodrow's visit to Grace Baptist Church today, I thought the following excerpt would be appropriate:

"Missions is not the ultimate goal of the church. Worship is. Missions exists because worship doesn't. Worship is ultimate, not missions, because God is ultimate, not man. When this age is over, and countless millions fall on their faces before the throne of God, missions will be no more. It is a temporary necessity. But worship abides forever.

Worship, therefore, is the fuel and goal of missions..."  

--John Piper, the opening lines of his classic book on missions, Let the Nations Be Glad (available here:  http://www.amazon.com/Let-Nations-Be-Glad-Supremacy/dp/0801036410/ref=pd_sim_b_4) 

These lines from Piper have also inspired at least two songs:

(1) "Mission's Flame" by Matt Redman, for song: http://www.youtube.com/watch?v=qENs_lJFmXU; for lyrics: http://www.stlyrics.com/songs/m/mattredman20504/missionsflame929476.html
