When you serve, just by sharing the space with your mentor, there is impartation. Impartation is not only through the laying of hands, just by breathing the same air with your mentor, you receive.
2 Kings 3:11 But King Jehoshaphat of Judah asked, “Is there no prophet of the LORD with us? If there is, we can ask the LORD what to do through him.” One of King Joram’s officers replied, “Elisha son of Shaphat is here. He used to be Elijah’s personal assistant.”
To be a personal assistant does not mean you are called but the officer believed that just by Elisha moving around with Elijah, he caught the anointing of Elijah. Servanthood requires an honest heart and dedication.
