Jesus Christ (Peace be upon Him) clearly denies in the Bible that he performed miracles on his own. Instead, there are statements attributed to Jesus Christ (Peace be upon Him) in the Bible in which he says quite the contrary. He emphasized that God Almighty gave this ability to him, as mentioned in
Gospel of John Chapter 14 Verse 28: My Father is greater than I
Gospel of John Chapter 10 Verse 29: My Father, which gave them me, is greater than all
Gospel of Matthew - 12:28: I cast out Devils by the spirit of God
Gospel of Luke - 11:20: I with the fingers of God cast out Devils
Gospel of John - 5:30: I can of mine own self do nothing, as I hear I judge and my judgment is just because I seek not my own will but the will of the Father who sent me.
Gospel of John 10:25-39: It is made very clear in the Bible by Jesus himself that he is a man, sent by God, and everything he says he hears, everything he teaches such as the doctrine is not his, and everything he does such as miracles is from God. also demonstrate that fact when Jesus himself says Many good works have I showed you from my Father.
Gospel of John 17:1-3: These words spake Jesus, and lifted up his eyes to heaven, and said, Father, the hour is come; glorify thy Son, that thy Son also may glorify thee: As thou hast given him power over all flesh, that he should give eternal life to as many as thou hast given him. And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent.
All these verses of the Bible make it clear that whatever miracle Jesus (Peace be upon Him) performed was only by the will of Almighty God and by himself he could do nothing whether it is giving life to the dead or healing the lepers or the blind or any other miracle.
A similar message about Prophet Muhammad (Peace be upon Him) is mentioned in the Qur'an in Surah Najm- 53:3,4:
Qur'an in Surah Najm- 53:3 - "Nor does he say (aught) of (his own) Desire."
Qur'an in Surah Najm- 53:4 -"It is not but a revelation revealed."
