Once upon a time, they brought a demon-possessed boy to Jesus. Mark tells the story:
And when the boy saw Jesus, immediately the spirit convulsed him, and he fell on the ground and wallowed, foaming at the mouth. So Jesus asked his father, “How long has this been happening to him?”
And he said, “From childhood. And often he has thrown him both into the fire and into the water to destroy him, but if You can do anything, have compassion on us and help us.”
Jesus said to him, “If you can believe, all things are possible to him who believes.”
Immediately the father of the child cried out and said with tears, “Lord, I believe; help my unbelief!”
When Jesus saw that the people came running together, He rebuked the unclean spirit, saying to it, “Deaf and dumb spirit, I command you, come out of him and enter him no more!” Then the spirit cried out, convulsed him greatly, and came out of him. And he became as one dead, so that many said, “He is dead.”
But Jesus took him by the hand and lifted him up, and he arose.
In the midst of trial, it is often very hard to get yourself to 100% certainty that God is going to come through. We struggle with this. So did the boy’s father. He had no plan B at all — Jesus was his last hope — and yet, he cannot bring himself to trust all the way.
But the thing to notice here is what Jesus does.
Jesus does not say, “Come back when you have no more doubts.” Jesus hears his prayer, and answers it.
Trust Jesus enough to show up. Trust Him enough to ask. And see what He will do.
