WOW! Well, like you said in your second reply, why should you have to call him! We have to accountable for our own actions. The Lord may be making room from your brother! My father pastors and we struggled for years with uncommitted musicians until God raise up my little brother! He wasn't the fast finger runner at the time, but he held the song! As he grew, he's now a bad musician and they love him to pieces! Its all about God's timing! As for the uncommitted musician, employers look at it as No call, no show and write that on the letter of termination. Just be prayerful, speak with your leadership and see how they want to handle it! Consistency is KEY in ministry! Blessings to you and I pray this works out QUICKLY!
