God anoints, chooses and appoints people for a specific purpose; thus He installs a person into an office. That office may be that of a king, priest, or prophet.

[Jeremiah 1:4-5] Now the word of the LORD came to me saying, [5] “Before I formed you in the womb I knew you, and before you were born I consecrated you; I have appointed you a prophet to the nations.” This kind of prophetic anointing happens in heaven before the time of planet earth.

[Job 38:7, 21] When the morning stars sang together and all the sons of God shouted for joy? [21] You know, for you were born then, and the number of your days is great!

To the natural man these portions of scripture may sound mystical, outlandish and metaphoric; and that is so because we live in time, geographical space and in 24-hour intervals of time. Once we come out from this mentality our orientation will change from purely physical to spiritual. God in His absolute omniscience forces all things. He looks at all things from the beginning to the end of human history, which includes all eras. When He turned that one molecule into motion that molecule was the all-containing seed. God is one and He works on the basis of oneness, which is logic and complete understanding of all things. He created them and therefore He knows all things in their primordial original state. He knows what they are capable of, He knows all cons and pros. He also knows who is His overcomer and who is not. He is gracious and kind, slow to anger and abounding in lovingkindness. Therefore, Job knew what God knew, but lost that revelatory knowledge when he left his mother womb.

Flesh can steal from us the original heavenly knowledge. But God said that Job knew; and that the number of his days is much greater than the number of earthly years, timeless and innumerable.

Jeremiah was God’s prophet as soul in heaven. God knew Jeremiah long before his conception and birth. Other prophets can anoint new prophets, but they must act in accordance with God’s instructions. God told Elijah to anoint Elisha in his place. The instruction was clear, not next to Elijah, but instead of. [1 Kings 19:15-16] Elisha the son of Shaphat of Abel-meholah you shall anoint as prophet in your place.

Once anointed that anointing is irrevocable; it can only be terminated by departure or death; however, it can be passed on to the next, of so God instructs. Before Elijah was taken to heaven in his stead he installed Elisha as a prophet.

[Romans 11:29] for the gifts and the calling of God are irrevocable. - This Paul spoke about the anointing of Israel and the Jewish people. Anointing is never for the self, but for others. God uses His annointed vessel for another; in this case God chose Israel for the World.
