Have you ever been in a worship service where the worship leader felt disconnected? Fake?
Maybe they seemed more into their music than their God. Maybe they seemed to be all about themselves rather than Jesus.
Whatever the case, sincerity is so important. Where you may lack a certain level of skill, your sincerity and passion for Jesus will make up for it.
I’m not saying your musical growth isn’t important. If you can’t sing on key or play your I IV V chords, no one will want to worship with you. But your church is looking for more than a good show and a fun sing-a-long. They are starving for God.
