Mark 9v20-23
And they brought the boy to him (Jesus). And when the spirit saw him, immediately it convulsed the boy, and he fell on the ground and rolled about, foaming at the mouth. And Jesus asked his father, “How long has this been happening to him?” And he said, “From childhood. And it has often cast him into fire and into water, to destroy him. But if you can do anything, have compassion on us and help us.” And Jesus said to him, “‘If you can’! All things are possible for one who believes.”

There is a constant theme throughout the gospels that Jesus seeks faith in those he heals. Belief is the key to seeing the miracles of God come to life in our situations. No matter how big or how far gone a situation may seem it is possible for one who BELIEVES. These are words directly out of the mouth of Jesus and we must respect and take them to heart. Our God created the earth, able to sustain billions of people He can take care of our struggles, we just have to believe it.
