The Point of Praise

A question skeptics ask religious people, a question many religious people have quietly asked, myself included: What is the point of praise? Doesn't God know God is great without us blabbering on about it? Wouldn't God, like any properly modest person, say to our hymns and, "Glad you like me, but hell, enough's enough!"
We forget about the majesty of God. In the midst of "Jesus is my boyfriend" culture and music-- (seriously, one Christian writer said we need to go on dates with Jesus and make sure to shave our legs for him because he deserves to see his princess all dolled up. Gross! I'm not shaving just for Jesus, that's for sure. And what, may I add, if you're a guy and not a metrosexual?!)-- we forget about John's vision:
 "I saw one like the Son of Man, clothed with a long robe and with a golden sash across his chest. His head and his hair were white as a white wool, white as snow; his eyes were like a flame a fire, his feet were like burnished bronze, refined as in a furnace, and his voice was like the sound of many waters. In his right hand he held seven stars, and from his mouth came a sharp, two-edged sword, and his face was like the sun shining with full force. When I saw him, I fell at his feet as though dead" (Rev 1:13-17). 
God is not our imaginary friend. God is the living God infinitely beyond our comprehension. Praise and worship are one level an assent to the fact of God's greatness, a fact unchanged by our worship or lack thereof. 
But that helps us see the original question-- why does God care about our praise-- in a whole new light. Why, indeed? Why does the Master of the Universe-- to use the Jewish phrase, and Jews are so much better at this reverence thing than we are-- give a flying flip whether I worship him or not? I'm just a speck on the cosmic landscape. As the psalter says:
"When I look at the heavens, the work of your fingers, the moon and the stars that you have established: what are human beings that you are mindful of them, mortals that you care for them?" (Ps 8:3-4)
As a mother loves even a chicken-scratch, construction paper Mother's Day card, so God loves our worship. He cares about our worship because he cares about us. He wants us to praise him because he wants us-- and not in the Jesus is my boyfriend way, but in this way:
"By the mercies of God, present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship" (Rom 12:1). 
He doesn't want our unshaved legs, or even just a couple pretty hymns on Sunday. He wants all of us, and part of that surrendering ourselves over to God includes worshipping the God whose glory is beyond compare, whose love for us nailed his Son to the cross.
But event the fact of the question-- What's the point of praise?-- betrays our rugged, unholy American productivity. Everything has to have a purpose, a point. But relationships don't work that way. Relationships don't have a point, and worship certainly doesn't have a point. There are times to work hard for the kingdom, interceding boldly for others, asking God for help, and generally striving. But there are times to just praise God. As Scripture says: 
"Blessed be the God and Father of our Lord Jesus Christ, who has blessed us in Christ with every spiritual blessing in the heavenly places" (Eph 1:3).
The Jewish prayer formulation, "Blessed be God..." highlights the uselessness of praise. How can we bless the God who already gives us every blessing? But God wants us to bless him anyway. Because he loves us with the love that "surpasses knowledge" (Eph 3:19). 
Blessed, indeed, be God!
