In this passage of scripture, Elijah is being taken up by a whirlwind on a chariot of fire and his successor, Elisha has picked up the dropped mantle. The mantle automatically marked a man as a prophet, or a spokesman for God and this mantle was a symbol of Elijah's power as well as, his authority as a prophet. It is also known as a symbol of sacrifice and commitment. Before Elijah’s departure, it had already been established and purposed by God that Elisha would succeed him. He had been anointed to take over; although, it is hard to see by Elisha's response here in the scripture. Elijah had been being with him daily for years as a father, a teacher, and a confidant and watching him ascend into the heavens could not have been easy. Elijah passing on the mantle symbolizes the passing of prophetic authority which signifies that he was literally transferring his prophetic ministry to his student, Elisha, the man chosen and anointed by God to succeed in his stead.
Jesus has done the same; He has spiritually transferred that mantle to us, his heirs, to carry on in His stead until He returns. No, we don't have a physical mantle to speak of, but the Spirit of God is our mantle, our source of power, our source of authority, and our source of strength for what He has purposed for us. Oftentimes, the Lord calls us to do more than we think we can or are able to do, but He always supplies us with the strength and equips us for kingdom work. He is looking for someone to pick up the mantle with power and authority. He needs someone with passion and fervor; someone with the same obedience, sacrifice and commitment of an Elijah and an Elisha; someone who is bold and confident that will walk in authority; someone will speak, live, and walk in truth, as well as teach the truth with compassion, grace, and love.
