Does God Heal Unbelievers? (Gospel of John #58)

John 9:35-38 NKJV
“Jesus heard that they had cast him out; and when He had found him, He said to him, “Do you believe in the Son of God?” He answered and said, “Who is He, Lord, that I may believe in Him?” And Jesus said to him, “You have both seen Him and it is He who is talking with you.” Then he said, “Lord, I believe!” And he worshiped Him.”
