So just where is the prayer to Elijah in Heaven? Even if he "took the prayer" with him then it is still not that of being prayed to in Heaven and able to hear all such, which was and remains the issue. But here there is no postal delivery service. The more Caths desperately to to provide what they can only wish the Spirit of God did then the worse it makes them look.
Did Elijah have the authority to give a double portion of his spirit to Elisha ? Who is the spirit of Elijah
It is God's Spirit, His anointing, of which a person can realize different measures and gifts. "For he whom God hath sent speaketh the words of God: for God giveth not the Spirit by measure unto him." (John 3:34)
And God can gift and entrust people with the power to convey His Spirit, thus "Ananias went his way, and entered into the house; and putting his hands on him said, Brother Saul, the Lord, even Jesus, that appeared unto thee in the way as thou camest, hath sent me, that thou mightest receive thy sight, and be filled with the Holy Ghost." (Acts 9:17)
It was not simply or necessarily a matter of authority as to giving a double portion, but of prophetic foreknowledge of what God would do if Elisha continued on with his master. Taking up he mantle of Elijah represented authority.
