When they came to the other disciples, they saw a large crowd around them and the teachers of the law arguing with them. As soon as all the people saw Jesus, they were overwhelmed with wonder and ran to greet him.
“What are you arguing with them about?” he asked.
A man in the crowd answered, “Teacher, I brought you my son, who is possessed by a spirit that has robbed him of speech. Whenever it seizes him, it throws him to the ground. He foams at the mouth, gnashes his teeth and becomes rigid. I asked your disciples to drive out the spirit, but they could not.” . . .
He replied, “This kind can come out only by prayer.”
Mark 9.14-18 & 29
The disciples in this passage are trying to climb Mount Everest while practicing their spiritual disciplines on an anthill. Jesus tells them that some exercises can only be achieved by those who have conditioned themselves to trust in God for their help. Only those who will allow the lordship of God to rule in their lives will have access to the great power of God.
We are not told whether the disciples were annoyed that their easy-come-easy-go spirituality wouldn’t hold up when they were face-to-face with Satan. But their failure should speak clearly to us. The greatest achievements of the saints are always the outgrowth of total commitment.
What are the requirements that make for utter discipline? Paul rehearses the rigours of such discipleship with Timothy, ‘Endure hardship with us like a good soldier of Christ Jesus’ (2 Timothy 2.3) A soldier is one who has trained and prepared for battle. A soldier is familiar with weapons and ready to fight to the death. Does our spiritual walk make us look like boot camp recruits? Or do we find that our discipline has grown soft and ineffectual?
Those who want to achieve great things for God need to practice the great disciplines of spirituality. Jesus said that prayer and devotion to God are the real evidences of a robust inner faith. Self-control is the first step of spiritual discipline. We must practice and prepare ourselves for the coming battles. If we cannot control our appetites, we can hardly be expected to enter into spiritual combat that tries even the souls of those who pray and fast.
