Mark 9:20 And they brought him unto him: and when he saw him, straightway the spirit tare him; and he fell on the ground, and wallowed foaming.
The young man was brought to Jesus, because no one else could heal him.
Mark 9:21 And he asked his father, How long is it ago since this came unto him? And he said, Of a child.
Mark 9:22 And ofttimes it hath cast him into the fire, and into the waters, to destroy him: but if thou canst do any thing, have compassion on us, and help us.
A destructive spirit, in him from childhood, seeking to destroy him. We need to pray for our children, for satan desires to destroy them and many are destroyed through suicide and wrong choices.
Mark 9:23 Jesus said unto him, If thou canst believe, all things are possible to him that believeth.
All things are possible if we believe that God is able. Jesus spoke of faith as an intercessor. This goes along with Malachi's prophecy:
Mal 4:6 And he shall turn the heart of the fathers to the children, and the heart of the children to their fathers, lest I come and smite the earth with a curse.
Unbelief allows satan to continue to curse and if unbelief is widespread, God himself will seek our attention by cursing the earth; Perhaps with earthquakes, tornados, storms and floods.
Mat 24:6 And ye shall hear of wars and rumours of wars: see that ye be not troubled: for all these things must come to pass, but the end is not yet.
Mat 24:7 For nation shall rise against nation, and kingdom against kingdom: and there shall be famines, and pestilences, and earthquakes, in divers places.
Mat 24:8 All these are the beginning of sorrows.
Mark 9:24 And straightway the father of the child cried out, and said with tears, Lord, I believe; help thou mine unbelief.
An excellent prayer, I believe, I have a little faith, Lord increase my faith.
Mark 9:25 When Jesus saw that the people came running together, he rebuked the foul spirit, saying unto him, Thou dumb and deaf spirit, I charge thee, come out of him, and enter no more into him.
The people came running together, were they together in faith? Or would theybe of unbelief seeking to stone him? Immediately Jesus rebuked the foul spirit, he named it and commanded it to come out and not return. How tragic if it were to return. Jesus sealed the entrance. To be permanently sealed we need the sealing of his Holy Spirit.
Mark 9:26 And the spirit cried, and rent him sore, and came out of him: and he was as one dead; insomuch that many said, He is dead.
The devil is stubborn and reluctant to give up what he once had. Sometimes it is painful to remove a bad spirit, but well worth it. Do not let a foul spirit keep you in bondage.
Mark 9:27 But Jesus took him by the hand, and lifted him up; and he arose.
He looked like he had no life, but when Jesus reached for his hand he arose. When Jesus reaches for our hand, we receive new life. Faith brought his hand and Jesus cast out the devil.
Mark 9:28 And when he was come into the house, his disciples asked him privately, Why could not we cast him out?
What's the trick Jesus? No trick, you must pay the price. We want results without doing what is required.
Mark 9:29 And he said unto them, This kind can come forth by nothing, but by prayer and fasting.
Prayer and fasting takes commitment and many do not want commitment, they take the easy road. Many do not make Jesus Lord of their life. Without Jesus we are powerless.
