When believers gather and worship the Lord, something wonderful happens. As Jesus said, "For where two or three are gathered together in My name, I am there in the midst of them" (Matthew 18:20). This does not mean that God lives in the church. In a sense He does, if we are speaking of believers. Because we are the church, He lives in us. But God doesn't live in a building.
But when God's people meet together, something changes. And what changes is that He manifests His presence in a supernatural way when we gather to worship Him and honor Him. And when we praise God together, whether it's in prayer or in prayer set to song in worship, we are doing what we were created to do. We are here to bring glory to God.
The Bible tells us that God has created all things for His glory (see Isaiah 43:7). And Psalm 106:1 says, "Praise the LORD
! Oh, give thanks to the Lord, for He is good! For His mercy endures forever."
Some might say, "Well, I don't really have a good voice." Neither do thousands of contestants on American Idol, but that didn't stop them. And it shouldn't stop you. When we sing to the Lord, it is not a performance for each other; it is a performance for an audience of one: God. And God isn't really all that impressed with your pitch or how loudly you sing. He is really far more interested in what is going on in your heart. So if that is all you can do, then that is good enough.
From Genesis to Revelation, our faith is one of worship. And in Heaven, we will sing (see Revelation 15:2–4). Worship is the language of Heaven. So let's start practicing now.
