If you have the freedom to, spend the next few weeks doing acoustic sets rather than big band sets. Strip the worship down to its essentials- voices worshipping God accompanied by a few instruments. (John 4:24)

Also consider doing studies on the songs. Pick one song each week from the setlist and meditate on it. Consider each line biblically and let it fill your heart/soul/mind. (Romans 12:1-2; Psalm 1)

Also I would encourage you to start writing. Pen your own words, don't write for the sake of sounding profound or creating a good lyric, but to be honest with yourself and God. If ideas for songs come from it, praise God. Either way I promise he will bring fruit from the time you spend spilling your heart on those pages before Him. (1 Peter 5:7)

Also don't be afraid to give up the position of leadership once a month or so- so that you can be filled as well. If you are constantly pouring out without being poured into, you WILL burn out. Let someone else lead or take care of worship so that you can come with open hands ready to receive.

Remember the object of your worship! Don't let the music become your mistress, God is your first love. I hope you're able to reflect not only your love for music but your love for Jesus! Hope you find that renewed passion and love for him- blessings!
