Another part of this verse talks about "one voice." When I read this I visualized a massive choir singing an Eric Whitacre piece (as seen in the video). Recently Whitacre put together a "virtual choir" in which people submitted videos from all over the world. When you simply listen to the track they sound as if they are all together performing as a choir. However, they are all in separate places. The harmonies are blending, the vowels are together, and the choir sounds as if it is "one voice" singing praise to God. It really is an amazing display of Gods provisions for us.
When dealing with music in general, relationships don't interfere with the harmonies and melodies being performed. Like in the video above we can be miles apart but still make the musical connection. But, when we turn our attention to bringing God the glory through our music and connection; we find that we cannot praise God one moment, criticize our pastor the next, and think we're offering acceptable praise to God through Jesus Christ. This is why I have come to the conclusion that in order to have significant worship we must put to death any selfishness that is in us - so that Christ might be seen more clearly seen through us.
Often our view of who we are is completely different from others view of us. Sin is deceptive in this capacity. Most of us have "blind spots" to our imperfections. Sometimes it takes a friendly nudge or an kind gesture to help us see our "blind spots" so we can avoid a major crash! We should thank God daily for placing people in our lives that can help us see what we cannot see ourselves.

God's plan is always better than our own and I am convicted that He intends to use our relationships to make us more like His Son. In this process we must become more effective in serving the church and bringing God the glory!
