Matthew 15:31

Insomuch that the multitude wondered, when they saw the dumb speaking, the maimed whole, the lame walking, and the blind seeing: and they glorified the God of Israel.

Reference to "the God of Israel" indicates that those multitudes were largely heathen, or Gentile, corresponding to the population of the area. Significantly, Christ related his mighty works to the Father, gave him the glory, the credit, and the honor, and in fact did them in the Father's name. He said, "I am come in my Father's name, and ye receive me not: if another shall come in his own name, him ye will receive" (John 5:43). Christ always emphasized the origin of his work as being with God. In this perfect trait, he was "the messenger of the covenant" (Malachi 3:1). He was God's plenary representative on earth; indeed, he WAS God in flesh, reconciling the world unto himself.
