What is the purpose of Christian music? Many people will argue back and forth about the types of music that should be used in churches today.
I think this is the main thing: the whole purpose of Christian music is to praise our Lord. When we accept Jesus into our lives and submit ourselves to Him, and obey God, He fills us with the Holy Spirit and we will sing a new song!
And he hath put a new song in my mouth, even praise unto our God: many shall see it
and fear, and shall trust in the Lord... (Psalm 40:3)
It isn't something we have to work at. It's not something we have to cultivate inside of us. It's something that God puts in us, and it's a result of His redeeming us.
It's not the music that enables us to show our love and devotion to God -- those feelings are already there. Praise to God in music is just one part of our expressions of love to Him.
...Be filled with the Spirit; speaking to yourselves in psalms and hymns and spiritual songs, singing and making melody in your heart to the Lord.... (Ephesians 5:18-19)
So, what are you listening to, today?
