In one sentence, describe what the following article is about:

He came to save the lost by showing people they needed to believe in Him. Healing was one of the methods he used to show people that He had come from God, so that they should listen to Him, believe and do what He said to do.  Nicodemus: "We all know that God has sent you to teach us. Your miraculous signs are evidence that God is with you." John 3:2  Others: And many of the people believed on him, and said, 'When Christ cometh, will he do more miracles than these which this man hath done?' John 7:31  Jesus Himself said, But if I do his work, believe in the evidence of the miraculous works I have done, even if you don't believe me. Then you will know and understand that the Father is in me, and I am in the Father John 10:38  Our mission is the same as Jesus said, as we do the works that we have been sent to do: Heal the sick and preach the gospel Matthew 10:7-8 --  then people will believe that we have the information that they need to begin a relationship with God.

Summary:
Consider Jesus' mission.
