I have heard many say it is the faith of the person receiving the miracle that allows the miracle to manifest. This is not true it is the person speaking or ministering that the miracle comes through. Miracles are manifested out of the heart of the believer not the receiver.
Definition of Miracle: Hebrew means dunamis “Power, inherent ability” the Greek meaning semaino – to give a sign- God allows miracles to come through us to allow those who don’t believe an opportunity to believe in the all sufficient God. When a miracle is done it is out of the already believing person’s heart the power of God moves through.
