You might think that the only one responsible for leading worship at church is the worship leader. Congratulations! Whether you like it or not, if you're on stage, people are looking to you for direction. All musicians. Everybody.
I've always had a complicated relationship with face-melting solos in church. Maybe you have too?
Let creativity in instrumentation ever be part of the evolving beauty of our Creator continually revealed in music, and let that creativity ever support the worshipers' voices as we glorify God in song. But let it not be executed in such a way that it detracts from a single word being proclaimed. In other words, whatever instrument you play, play in the name of Jesus (Colossians 3:17).
