Worship in Music
The Bible does not condone or condemn any specific music style. However, worship must be God-focused and not man focused.
Music is a testimony of the goodness of God and our praise is an acknowledgment of the value of who God is, what He has done, and His worthiness and majesty over all creation. Worship and praise consists of at least one of three basic elements: 1. Adoration and acknowledgement for who God is or what God has done. 2. Appreciation to God for His love toward us. 3. A testimony to others about who God is or what He has done for us.
It is appropriate to sing songs that are spoken directly to God as praise. It is equally appropriate to sing about what God has done as though it were a testimony to others. I believe that all three of the above styles of worship are necessary to complete the testimony of praise in the church.
