Music is powerful for many reasons. When the Lord wanted the children of Israel to remember His Word, He told Moses, “Now therefore, write down this song for yourselves, and teach it to the children of Israel; put it in their mouths, that this song may be a witness for Me against the children of Israel." (Deuteronomy 31:19) Songs can be remembered for many years, even when they have not been heard recently.
We must be careful when mixing secular songs with the gospel message. Contemporary music often samples other artists whose message does not bring glory to God. While this has been done in an attempt to reach the world, this is not our mandate. When we lift up Jesus, He will draw others to Himself.
These songs may take people to a place in time in their minds when they had a stuggle with sin in a particular area. Funky baselines of yesteryear often lead a congregation into dancing that is reminiscent of the parties and clubs that they once visited. The body naturally responds to music with movement. We will often find ourselves singing familar songs before we realize it. In the ministry of movement, let us always take care to lead others to Christ.
3 John 1:11 (NKJV)
"Beloved, do not imitate what is evil, but what is good. He who does good is of God, but he who does evil has not seen God."
Psalm 149:1 (NKJV)
"Praise the LORD! Sing to the LORD a new song, and His praise in the assembly of saints."
