The servant of God must have enough time separated to hear from God. As the ministry grows, time will come when you have to have others around you to assist not to control you. Leaders helps to lift some of the weight from you. They make sure things are running well and prepare the church or service. A tired pastor cannot be effective. Exodus 18:17-18 So Moses’ father-in-law said to him, “The thing that you do is not good. Both you and these people who are with you will surely wear yourselves out. For this thing is too much for you; you are not able to perform it by yourself.
Depend on the Holy Spirit to show you the right people to be leaders else you’ll get people who want to run you. When you are called, there things God want to achieve and He is speaking to you not a committee. Acts 13:2 As they ministered to the Lord and fasted, the Holy Spirit said, “Now separate to Me Barnabas and Saul for the work to which I have called them.”
