Numbers 27:18-20 And the LORD said to Moses: “Take Joshua the son of Nun with you, a man in whom is the Spirit, and lay your hand on him; set him before Eleazar the priest and before all the congregation, and inaugurate him in their sight. And you shall give some of your authority to him, that all the congregation of the children of Israel may be obedient.
Church leadership is not run by a democratic process, elect those who carry your spirit as directed by God otherwise somebody will change the vision of the ministry. Exodus 33:11 So the LORD spoke to Moses face to face, as a man speaks to his friend. And he would return to the camp, but his servant Joshua the son of Nun, a young man, did not depart from the tabernacle. When Moses came down from the mountain, Joshua was the first to experince the anointing moved with him, hence he became the one to carry the vision. A lot of ministries collapse once the Set Man passes on because they did not introduce the one to take over after their passing. People must know who will take over and get used to him being around.
A group of prophets tried to discourage Elisha from following Elijah but he understood his relationship with his mentor. 2 Kings 2:13-15 He also took up the mantle of Elijah that had fallen from him, and went back and stood by the bank of the Jordan. Then he took the mantle of Elijah that had fallen from him, and struck the water, and said, “Where is the LORD God of Elijah?” And when he also had struck the water, it was divided this way and that; and Elisha crossed over. Now when the sons of the prophets who were from Jericho saw him, they said, “The spirit of Elijah rests on Elisha.” And they came to meet him, and bowed to the ground before him.
