But some will say it is impossible to have total faith in God and not at least have some doubt. Mark 9 tells us of the account when Jesus delivered the mans son who was posessed. His disciples could not deliver the boy and later Jesus tells them why- "because of your unbelief". We have a responsibility to have faith! The man told Jesus "but if thou canst do anything, have compassion on us, and help us". The man tried to put the responsibility on Jesus and Jesus flipped it right back to him and said "if thou canst believe all things are possible to him that believeth. The man then cried out "Lord I believe; help thou mine unbelief. Did he receive his miracle? Yes he did.
Doubt that isnt dealt with can and will destroy us! The man got his miracle because despite the doubt he was experiencing, he was dealing with it and choosing to believe! God knows where we are and is ever ready to meet us in that very place as long as we are willing to deal with the doubts and trust Him! In this regard Doubt does build our Faith!
Jesus is Lord
