...help me overcome my unbelief

“What is all this arguing about ?” Jesus asked.

One of the men in the crowd spoke up and said, “Teacher, I brought my son so you could heal him. He is possessed by an evil spirit that won’t let him talk. And whenever this spirit seizes him, it throws him violently to the ground. Then he foams at the mouth and grinds his teeth and becomes rigid. So I ask your disciples to cast out the evil spirit, but they couldn’t do it.”

Jesus said to them, “You faithless people! How long must I be with you? How long must I put up with you? Bring the boy to me.”

So they brought the boy. But when the evil spirit saw, Jesus, it threw the child into a violent convulsion, and he fell to the ground, writhing and foaming at the mouth.

“How long has this been happening?” Jesus asked the boy’s father.

He replied, “Since he was a little boy. The spirit often through him into the fire or into the water, trying to kill him. Have mercy on us and help us if you can.”

What do you mean, “If I can?” Jesus asked. “Anything is possible if a person believes.”

The father instantly cried out. “ I do believe, but help me overcome my unbelief!”
