This little Greek woman, no doubt, had heard of Him, heard of Jesus, the great revival. A young Prophet coming up in Galilee, from Nazareth, and was showing great signs and wonders. She had heard of Him, and, “faith comes by hearing.” This Syrophenician woman, being a Greek. Faith finds sources that others don’t see. When she heard, she believed. She might have heard of a neighbor’s girl being healed of epilepsy, which the child had, and they might have heard of this epileptic being healed. So her daughter had need of healing, and she had heard Jesus could do it.
For, He was God’s Word made flesh! Saint John 1, “In the beginning was the Word, and the Word was with God, and the Word was God. And the Word was made flesh and dwelt among us. The same yesterday, today, and forever!” He was there to reveal the promises of God for His day.
He is here tonight to vindicate and to reveal every promise that God made for this age. He is here to do it. He was in the days of the prophets. He was in Moses, He was in David, He was in Elijah, He was in the rest of them, to reveal God’s promise of that age. God lotted His Word to each age, and He sends a prophet, and the Word goes to the prophet and straightens it out, and that’s exactly what He has done through all ages. And He is God, and changes not. Jesus Christ is that Prophet tonight that stands among us. He is the One here in the form of the Holy Ghost, Who knows everything, and can reveal anything that He desires to do.
She believed this, no matter how much people didn’t believe it.
Faith finds a source that other people don’t know nothing about. When a man has got faith in God, he’s got a hold of something that he can’t explain it. It’s something that he’s got a hold of. He cannot push it, or shove it, or pull it. It takes Him. That’s the way faith is, when a man really got faith in God, it finds that source that others don’t see.
