"And in that same hour he cured many of their infirmities and plagues, and of evil spirits;
and unto many that were blind he gave sight. Then Jesus answering said unto them, Go your way, and tell John what things ye have seen and heard; how that the blind see, the lame walk, the lepers are cleansed, the deaf hear, the dead are raised, to the poor the gospel is preached" (Luke 7:21-22).

John the Baptist sent two disciples to Jesus with the question, "Art thou he that should come? or look we for another."

Apparently John had allowed some doubts to enter his mind concerning Jesus. He had announced Jesus at Jordan, "Behold the Lamb of God," but now he was in doubt.

Instead of Jesus sending back just a simple answer, He demonstrates His power before these disciples.

They saw the blind given sight; they witnessed men delivered from infirmities, plagues and evil spirits. They were now able to return to John with positive proof for they had actually seen the power of God in demonstration.

There can be no greater proof than that of miracles which bear evidence of the power of God. The miracles gave proof of the true identity of our Lord.

Someone has said that the miracles performed by our Lord were His credentials. They were signs revealing His true nature and mission.

We can see the personality and nature of Jesus Himself in each of His miracles. For example:

1) The miracle of feeding the multitude reveals Him as the Bread of life;

2) The miracle of healing the blind man reveals Him as the Light of the world;

3) The miracle of raising Lazarus reveals Him as the Resurrection and the Life.
