And when they came to the crowd, a man came up to him and, kneeling before him, said, “Lord, have mercy on my son, for he is an epileptic and he suffers terribly. For often he falls into the fire, and often into the water. And I brought him to your disciples, and they could not heal him.” And Jesus answered, “O faithless and twisted generation, how long am I to be with you? How long am I to bear with you? Bring him here to me.” And Jesus rebuked the demon, and it came out of him, and the boy was healed instantly. Then the disciples came to Jesus privately and said, “Why could we not cast it out?” He said to them, “Because of your little faith. For truly, I say to you, if you have faith like a grain of mustard seed, you will say to this mountain, ‘Move from here to there,’ and it will move, and nothing will be impossible for you” (Matthew 17:14–20).

Spiritual warfare cannot be merely a pastime or activity. It must be a lifestyle. However, it is not a lifestyle of looking for demons lurking around every corner or hiding beneath every rock. It is about walking by faith moment by moment, ready to stand with Jesus against the wiles of Satan whenever necessary. The key lesson of Matthew 17:14–20 is our need to walk in faith and saturate our lives in prayer.

The whole armor of God is not a costume we put on for special occasions. One of the ministries I serve on at my church is the prayer team at a special monthly service. We can expect to rebuke demons who are afflicting some of the people who come up for prayer. However, I cannot just strap on the armor of God when I arrive at church at 7:30 and take it off at the end of the service. Spiritual warfare demands that I wear the whole armor of God 24 hours per day, seven days per week, 52 weeks per year.

How do we keep the armor of God on? The same way we receive it: by walking in faith in Jesus.

As I mentioned in an earlier post, wearing the whole armor of God is synonymous with clothing ourselves in Christ. “So, as we seek to put on the whole armor of God, we are clothing ourselves in the very life of Christ.” Every piece of the whole armor of God is a facet of Jesus’ nature. We have the belt of truth; Jesus is the Truth. We have the breastplate of righteousness; Jesus is our righteousness. We have the shoes of peace. Jesus is our peace. We have the shield of faith; Christians walk by faith in Jesus. We wear the helmet of salvation; Jesus’ name is the only name under heaven by which men must be saved. We carry the sword of the Spirit, which is the Word of God; Jesus is the incarnate Word of God. As we walk with Jesus, every element of the spiritual armor protects us, because Jesus is with us.

During His earthly ministry, Jesus performed numerous miracles: healing the sick, casting out demons, raising the dead, etc. It can seem as though nothing would stop Him from performing miracles. However, the Bible mentions one obstacle which could reduce the number of miracles Jesus could perform:

And he could do no mighty work there, except that he laid his hands on a few sick people and healed them (Mark 6:5).

When Jesus visited Nazareth, people would not believe that Joseph and Mary’s son was now a great man of God. Their doubt limited Jesus’ power. Faith is essential for those who wish to see a move of God. Sometimes, lack of faith will prohibit you from receiving the blessing God is offering. At other times, it will keep you from being effective in spiritual warfare. When the people of Nazareth would not believe, they could not receive the blessings of Jesus’ miraculous power. When the disciples could not believe, they could not perform the miracles Jesus had empowered and authorized them to perform (Matthew 10:1).

People may blame the disciples’ failure on several things. Some say that the disciples failed because they were not yet baptized in the Holy Spirit. This would not occur until Pentecost, 10 days after the resurrected Jesus had ascended into heaven. During Jesus’ earthly ministry, the disciples could perform some miracles, but they did not have the full blessing of the Holy Spirit’s lasting presence and power within them. This is at least part of the problem. The baptism in the Holy Spirit will help increase our faith.

Another factor many may mention is a lack of prayer and fasting. A few preachers will point to Matthew 17:21, which does not appear in the earliest Greek manuscripts of the Gospel: “But this kind never comes out except by prayer and fasting.” Many English Bible translations leave this verse out or place it in a footnote since it seems possible that it was added by a later scribe and not written by Matthew himself. Whether Jesus actually said this or not, it is secondary to the main point of this passage: The disciples’ lack of faith prohibited the child’s deliverance. Prayer and fasting are important: They are valuable tools to help a believer’s faith to grow. Christians are commanded elsewhere in the New Testament to pray, and we are urged strongly to fast. But, the key is to grow in faith.

Faith empowers us to walk in the miraculous power of God. Earlier, when Jesus walked on water, Peter asked for permission to join Him:

And Peter answered him, “Lord, if it is you, command me to come to you on the water.” He said, “Come.” So Peter got out of the boat and walked on the water and came to Jesus. But when he saw the wind, he was afraid, and beginning to sink he cried out, “Lord, save me.” Jesus immediately reached out his hand and took hold of him, saying to him, “O you of little faith, why did you doubt?” And when they got into the boat, the wind ceased (Matthew 14:28–32).

Have you ever noticed that, for a while, Peter actually walked on water, just like Jesus? In fact, it was not only a few steps: Jesus was far enough from the boat that the disciples were not sure it was really Him. Yet, Peter walked all the way from the boat and came to Jesus. While walking to Jesus, Peter was probably thinking, “I’m walking to Jesus. If He can walk on water, He can help me walk on water.” While returning to the boat, he changed his perspective and thought, “Wait a minute. What am I doing out here? Look at the size of those waves! That wind is insane! How did I get so far from the boat? This is impossi…glub…glub…glub.” While he kept his eyes on Jesus, Peter could walk in the miraculous power of our Lord. When he looked at the circumstances and took his eyes off of Jesus—even though He was right next to him—he fell out of supernatural power and back into the normalcy of the natural life, as if God was not present.

The point of this is that we must walk by faith. Spiritual warfare is a battle of faith. Faith is not just intellectual knowledge (in fact, head knowledge can be an obstacle to true faith). We keep our eyes on Jesus, marching with Him into battle to reveal His life-giving power to a world in bondage to darkness and death.
