It will take more work, but it can be acheived. It has only been within the past 20 years that worship leaders have been leading from their instruments. If God has called you to do it, He will equip you with the gifts and tools to do it. Or He may bring you someone to help where you may need it. We need worship leaders who have a heart and understanding of worship.
Some churches have music directors who do all the music rehearsals and lead the band and vocals.
All the worship leader does is lead the worship. An options for you to consider. We will pray for God to lead and guide you during this time. By posting a message to this forum users agree to abide by the guidelines section of the board's help file.
