The third step in the prophetic calling is the promise of divine support and empowerment for the mission through the infilling of the Spirit of wisdom, boldness, understanding, counsel, knowledge, fear of God and knowledge. In addition, credible supernatural signs are given to the prophet to reassure and dispel any doubt in their mind. Moses in the book of exodus request evidence from God to authenticate his calling before the elders of Israel in Egypt, which God gave to him.

“Then Moses answered [the Lord] and said, “What if they will not believe me or take seriously what I say? For they may say, ‘The Lord has not appeared to you.’” 2 And the Lord said to him, “What is that in your hand?” And he said, “A staff.” 3 Then He said, “Throw it on the ground.” So, Moses threw it on the ground, and it became a [living] serpent [like the royal symbol on the crown of Pharaoh]; and Moses ran from it. 4 But the Lord said to Moses, “Reach out your hand and grasp it by the tail.” So, he reached out his hand and caught it, and it became a staff in his hand— 5 [“You shall do this,” said the Lord,] “so that the elders may believe that the Lord, the God of their fathers, the God of Abraham, the God of Isaac, and the God of Jacob, has [most certainly] appeared to you.” The Lord also said to him, “Put your hand into your robe [where it covers your chest].” So, he put his hand into his robe, and when he took it out, his hand was [a]leprous, as white as snow. 7 Then God said, “Put your hand into your robe again.” So, he put his hand back into his robe, and when he took it out, it was restored [and was] like the rest of his body. 8 “If they will not believe you or pay attention to the evidence of the first sign, they may believe the evidence of the second sign. 9 But if they will not believe these two signs or pay attention to what you say, you are to take some water from the Nile and pour it on the dry ground; and the water which you take out of the river will turn into blood on the dry ground.”
Exodus 4:6-9

God empowered Jesus Christ for the mission of salvation by given him the power and authority to heal diverse diseases without any limitations coupled with the power to raise the dead through his word. These serves as the evidence base for his ministry as well as divine authentication of his ministry. No man, no Bishop, No Apostles, No Prophets, No Pastor till today has been able to replicate the fullness of the signs that God enabled Jesus Christ to perform seemingly effortlessly.

“How God anointed Jesus of Nazareth with the Holy Spirit and with great power; and He went around doing good and healing all who were oppressed by the devil, because God was with Him”.
Acts 10:38
