Ummm no, there you go taking away from scripture.
Mark 16:
19So then after the Lord had spoken unto them, he was received up into heaven, and sat on the right hand of God.
20And they went forth, and preached every where,
the Lord working with them, and confirming the word with signs following. Amen.
No man has the power do anything of themselves no matter how much they may believe. Only the holy spirit has the power to work through the believer. If belief alone was all that was needed then;
James 2:19 Thou believest that there is one God; thou doest well: the devils also believe, and tremble.
Acts 1:8 But
ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth.
If you were truly trying to discuss the subject and you didn't believe what I said then why not ask how my conclusion was made rather than simply denying it? How can any believer who lives by every word of God not know that it is the holy spirit that empowers the miracles and signs? Even Christ said it plainly;
John 14:
10Believest 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.
11Believe me that I
am in the Father, and the Father in me: or else believe me for the very works' sake.
12Verily, 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.
13And whatsoever ye shall ask in my name, that will I do, that the Father may be glorified in the Son. 14If ye shall ask any thing in my name, I will do it.
