Jesus gave us the keys to working the works of God. One basic key is to know that Jesus is in the Father, the Father is in Jesus, and that the Father did the works that Jesus delivered.
John 14:9 "Jesus saith unto him, Have I been so long time with you, and yet hast thou not known me, Philip? he that hath seen me hath seen the Father; and how sayest thou then, Shew us the Father?"
Note that even though the disciples (or at least Philip) had been with Jesus for 3 1/2 years or so, they still missed the key element that everything Jesus said and did was in accordance with the Father, and exactly and clearly represented the will of Father God-Abba-Daddy God.
KEY NO 1: John 14:10 "Believest thou not that I am in the Father, and the Father in me? the words that I speak unto you I speak not of myself: but the Father that dwelleth in me, he doeth the works. 11 Believe me that I am in the Father, and the Father in me: or else believe me for the very works' sake."
Jesus makes it clear that while Jesus did His part on earth, it was the Father (by Holy Spirit) that did the actual signs and wonders - the works - that Jesus did. Yet even the diciples were blinded to this key fact.
PROMISE: John 14:12 "Verily, verily, I say unto you, He that believeth on me, the works that I do shall he do also; and greater works than these shall he do; because I go unto my Father."
KEY NO 2: John 14:13 "And whatsoever ye shall aiteo-ask-demand as due by covenant promise in my name, that will I do, that the Father may be glorified in the Son. 14 If ye shall aiteo-ask-demand as due by covenant promise any thing in my name, I will do it."
Here Jesus gives authority that anything we demand as promised by the Father in the covenant word of God (meaning of aiteo) that Jesus would do it. This is how we heal the sick, lame, diseased and cast out devils. This is how we command any mountain to move per Mark 11:24
