Because it is what we were created for
Ps. 150:6 – Let everything that has breath praise the Lord.
Is. 43:6, 7 – Bring my sons from afar and my daughters from the ends of the earth– everyone who is called by my name, whom I created for my glory.
When we worship we enter into our ultimate purpose and final destiny. Just as birds are made to fly, fish are made to swim, and cars are made to drive, we were made to give glory to our Maker and Redeemer!
Because God Sings
Zeph. 3:17 – The LORD your God is with you, the Mighty Warrior who saves. He will take great delight in you; in his love he will no longer rebuke you, but will rejoice over you with singing.
At the end of the Last Supper Jesus and the others sang a hymn. – Matt. 26:30
There are many different Christian traditions and ways of expressing worship to God, but to me singing just doesn’t seem optional. Not only is it the most repeated command, but God Himself sings!
Having been made in the image of God it is in a Christ follower’s DNA to sing!
