The word of God has the power to accomplish many things including the restoration of our health. Jesus displayed this power when a certain noblemans son was near death and asked Jesus to go with him and heal his son,but it was only the words Jesus spoke that brought healing to the noblemans son! We learn from this story that it was also the faith to believe on the noblemans part was his son made whole!(John 4:46-54). So Jesus came again into Cana of Galilee, where he made the water wine. And there was a certain nobleman, whose son was sick at Capernaum. When he heard that Jesus was come out of Judaea into Galilee, he went unto him, and besought him that he would come down, and heal his son: for he was at the point of death. Then said Jesus unto him, Except ye see signs and wonders, ye will not believe. The nobleman saith unto him, Sir, come down ere my child die. Jesus saith unto him, Go thy way; thy son liveth. And the man believed the word that Jesus had spoken unto him, and he went his way. And as he was now going down, his servants met him, and told him, saying, Thy son liveth. Then enquired he of them the hour when he began to amend. And they said unto him, Yesterday at the seventh hour the fever left him. So the father knew that it was at the same hour, in the which Jesus said unto him, Thy son liveth: and himself believed, and his whole house. This is again the second miracle that Jesus did, when he was come out of Judaea into Galilee.

 We may think well that was Jesus the son of God and we are mere humans,but according to scripture that same power flows through us as well by the holy spirit given us and the faith we hold in Christ!It was displayed through Paul we see in the book of Acts as he proclaimed healing in the name of Jesus (Acts 19:11-17). And God wrought special miracles by the hands of Paul: So that from his body were brought unto the sick handkerchiefs or aprons, and the diseases departed from them, and the evil spirits went out of them. Then certain of the vagabond Jews, exorcists, took upon them to call over them which had evil spirits the name of the Lord Jesus, saying, We adjure you by Jesus whom Paul preacheth. And there were seven sons of one Sceva, a Jew, and chief of the priests, which did so. And the evil spirit answered and said, Jesus I know, and Paul I know; but who are ye? And the man in whom the evil spirit was leaped on them, and overcame them, and prevailed against them, so that they fled out of that house naked and wounded. And this was known to all the Jews and Greeks also dwelling at Ephesus; and fear fell on them all, and the name of the Lord Jesus was magnified. (Mark 16:15-20).

 In proverbs we learn as wisdom speaks that we are told to attend to the word and to keep them in our heart for it is life and health to our flesh!(Proverbs 4:18-23). But the path of the just is as the shining light, that shineth more and more unto the perfect day. The way of the wicked is as darkness: they know not at what they stumble. My son, attend to my words; incline thine ear unto my sayings. Let them not depart from thine eyes; keep them in the midst of thine heart. For they are life unto those that find them, and health to all their flesh. Keep thy heart with all diligence; for out of it are the issues of life.
