Green Berets. Rangers. SEALs. Delta Force. These special forces groups are part of the United States military. They are elite: highly trained with unique skill sets. Many of their important missions are carried out in total secrecy.

Two weeks ago, we acknowledged that we are in the middle of a massive spiritual war. Today, we thank God that we fight this war with the protection of special forces. Since the fifth century, Christians have observed the Festival of St. Michael and All Angels. We commemorate that God has sent Michael, one of the great archangels described in Scripture, and countless of his fellow angels to protect and serve mankind. Let us rejoice that followers of Christ have powerful allies!

Humility and pride are polar opposites. Pride exalts self at the expense of God and others. Humility exalts God and others at the expense of self. Pride is the essential vice, for it increases one’s hunger for all other sins. Humility increases one’s hunger for the forgiveness and healing found in Christ. The one who is proud demands to be served. The one who is humble is not content unless serving others. St. Augustine described it this way: “It was pride that changed angels into devils; it is humility that makes men as angels.”

As we see all Christ did to serve us, our hearts melt. Within us grows a Christ-like obsession to serve others, without counting the cost, without any desire to be repaid. Those who are in positions of Christian leadership understand that their leadership can only be achieved through service. For followers of Christ are humble servants.

Power is neither inherently good nor bad. Fire is powerful. The chef uses fire to create meals. But the arsonist uses fire to destroy homes. Nuclear fission is a powerful force. The engineer harnesses it, producing abundant electricity. The tyrant harnesses it, threating others with nuclear weapons. What matters is the purpose of the one who has that power.

Jesus has limitless power, as the numerous accounts of his miracles demonstrate. Those who witnessed those miracles understood that Jesus used his power for good. That doesn’t mean they all understood Jesus’ true purpose. Some thought Jesus’ purpose was to make this temporal life better. And while Jesus did that at times, his ultimate purpose was to save us from sin and give us the gift of eternal life. Followers of Christ see the true purpose of his power.

A loving father gives his son and daughter a list of rules and regulations. Chores, curfews, civilities, dress code—the father makes his will clearly known. The son strives to follow the rules for two reasons. 1) He wants to get his allowance. 2) He is afraid that if he breaks the rules, his father will punish him. The daughter strives to follow the rules, also for two reasons. 1) She believes her father established those rules not to control her but for her safety and blessing. 2) She wants to demonstrate how much she loves and trusts her father. Those two children’s actions might look almost identical. Their hearts are very different!

Likewise, following Christ is not simply a matter of outward observance of laws. It is a matter of the heart. The Law was given so we could see God’s heart and demonstrate how his heart has affected our own. The followership Christ seeks flows from hearts that have been radically transformed by God’s law and gospel. Christ wants his followers to be less like the son described above, and more like the daughter. This week we see that followers of Christ obey his law from the heart.

As Jesus concluded his Bread of Life discourse, many said, “This is a hard teaching. Who can accept it?” and walked away. Read carefully. They did not say the teaching was hard to understand. The meaning was clear enough. Jesus was teaching that the only chance to enjoy eternity in heaven is through a close connection to him. He is the only bread that gives eternal life. That isn’t hard to understand, but it is hard to accept. Eating this bread means reordering our lives so that Jesus is by far our highest priority. It means loving the Blesser infinitely more than his earthly blessings. It means realizing that Jesus is the only thing we really need. If we had nothing but him, we would not lack anything that ultimately matters.

Jesus watches the multitudes walking away from him. He turns to the Twelve—he turns to us this week—and he whispers, “You do not want to leave me too, do you?” May the Spirit give us the wisdom to answer, “Lord, to whom shall we go? You have the words of eternal life.”

Physical food is a blessing from God without which we would literally wither away and die. That is why Jesus lovingly and miraculously fed thousands of followers with only five loaves of bread and two fish. Yet, while physical food is a good thing, it is far from the greatest thing God provides us. The greatest blessing God provides is spiritual food. The best thing God gives us is his Son, the Bread of Life. Without that spiritual food, we wither and die in a much worse way.

This week we see the multitudes coming to Jesus looking for two things: ever more temporal blessings—full bellies, healthy bodies—and an explanation of how to gain them. Jesus explains the greater need for spiritual food. He assures us that there is nothing we do to earn it. Our Father urges us to come to him for our daily bread, asking him to provide for our temporal needs. But may we hunger most for our greatest need: spiritual food that Christ freely gives.

When a child asks a sibling to do something, there isn’t much certainty as to the results. The sibling might simply ignore the request. However, if that same child goes to a brother or sister with “Dad said so,” it’s a very different story! Now the father’s authority is behind the child’s request.

As believers carry out gospel ministry, encouraging others to turn to Christ in repentance, people might push back. “What gives you the right?” Maybe we ask that question ourselves. “I’m far from perfect. So, what gives me the right to talk about things like sin?” This week we are given the answer to that question. “Dad said so.” When our God calls us to do ministry, he also gives us authority. In calling us to ministry, God isn’t asking us to share our advice or our opinion or even our values. We are sharing God’s own authoritative Word. Gospel ministry is conducted by believers but with God’s own authority behind the effort.

If ministry involves serving others with love and compassion, you would think that people would respond only with glee and gratitude for the help they received. Sometimes, but not always. If you offer to help a family member who is having trouble paying his bills, he might be offended, wondering if you are implying that he is not a good provider. Likewise, if you try and share the gospel with someone, he might resent the message that he is a sinner in need of salvation. You are trying to minister to this man’s greatest need. Your intentions are loving. Yet he responds with rejection and resentment.

When our ministry efforts are met not with glee and gratitude but rejection and resentment, we are in good company. The prophets, apostles, and even Jesus himself all had those who responded negatively to their ministries. When that happens to us, it doesn’t mean our ministry is no longer meaningful. For if others do not appreciate our efforts to serve them, God still appreciates our efforts to serve him.

Usually, a kingdom advances and is secured through things like military might or political force or worldly wealth. It can be tempting to believe the same holds true in the kingdom of God. Perhaps we think churches would flourish if we had the right rulers passing and enforcing the right laws. Or we believe that for a church to do good requires a robust budget. Political force. Worldly wealth. This way of thinking is breathtakingly wrong.

We need God to give us the top-down faith that grasps the fact that the kingdom of God advances in ways that are imperceptible. Through something that seems insignificant to most—the gospel—the King of kings establishes his reign in human hearts. Even Jesus himself taught that the gospel seems unimpressive, for He often compared the gospel to a tiny seed. Yet within a seed is hidden life. As the seed of the gospel is planted, the largest of all kingdoms grows.
