Obey them that have the rule over you, and submit yourselves: for they watch for your souls, as they that must give account, that they may do it with joy, and not with grief: for that is unprofitable for you. Hebrews 13:17 KJV
A true pastor does not choose to be one. The office is not one that is by the choice of man but by the choice and call of God.
A pastor must watch over the souls entrusted to him and is held responsible by God Himself. He is answerable to no man, but is totally accountable to God.
His is a supernatural ministry gift enabled and empowered by none other than the Holy Spirit.
His authority is God given and he is anointed for the task.
Never take it upon yourself to be what God has not called you to be.
But, never run from His call upon your life.
