Mark 9:17 And one of the crowd answered Him, “Teacher, I brought You my son, possessed with a spirit which makes him mute; 18 and whenever it seizes him, it slams him to the ground and he foams at the mouth, and grinds his teeth and stiffens out. I told Your disciples to cast it out, and they could not do it.”
19 And He answered them and said, “O unbelieving generation, how long shall I be with you? How long shall I put up with you? Bring him to Me!” 20 They brought the boy to Him. When he saw Him, immediately the spirit threw him into a convulsion, and falling to the ground, he began rolling around and foaming at the mouth. 21 And He asked his father, “How long has this been happening to him?” And he said, “From childhood. 22 “It has often thrown him both into the fire and into the water to destroy him. But if You can do anything, take pity on us and help us!”
23And Jesus said to him, “ ‘If You can?’ All things are possible to him who believes.” 24 Immediately the boy’s father cried out and said, “I do believe; help my unbelief.” NASB
Few of us doubt that God performed all the miracles recorded in the Bible. We believe that in the beginning, God created the heavens and the earth. We believe in a world-wide flood and Noah’s rescue in the ark. We believe that David killed Goliath with a sling and we believe that Jesus walked on water.
Our problem is not believing that God ‘can’ perform miracles. Our problem is believing God ‘will’ perform miracles; especially when those miracles involve us. Sometimes we are like the father who – “Lord, I believe; help thou mine unbelief.” (Mark 9:24)
We read from the book of Hebrews that faith in God is essential in order for us to experience the working of His mighty power. The Bible says – “But without faith it is impossible to please him: for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him.” (Hebrews 11:6) Not only do we have to believe that God ‘is’ or that He ‘can’; we have to believe that He ‘will.’
The question was not – ‘Could Jesus do something?’ The question was – ‘Could the man believe that Jesus could do something?’ Did he have the kind of faith that is necessary to see a miracle?
