2 Samuel 22: A Shield for You and for Your Neighbor

Introduction

"You are my shield." That is the title of this message, preached at Hiratsuka Baptist Church in Japan during a worship service where adults and children worship God together. This month the church receives the Word from the same passage as the Sunday school: 2 Samuel 22:21-31.

In Sunday school, the children have followed the life of David: the young shepherd, the victor over Goliath, the man hunted by Saul who wanted him dead, the king who knew glory, then failure and suffering. A life with peaks and valleys. The song of 2 Samuel 22 is David looking back over that whole life.

The preacher pauses on two verses: verse 28, where God lifts up the humble and brings down the proud, and verse 31, where he is a shield to all who take refuge in him. The first speaks of peace, the second of protection. Both tell you where God stands when your life is nothing like a perfect circle.

Outline of the Message

1. One Psalm, Different Words

• A story is read by following its characters and events. A poem does not work that way: reading the same words, each person keeps a different word in their heart.
• In the same service, with the same psalm, one person receives comfort, another encouragement, and yet another a challenge.
• The preacher asks a simple question: as you listened to this psalm, did you find a word that makes you say, "That's me, today"?

2. Shalom, a Circle Without Distortion

• Verse 28: "You will save the afflicted people, but your eyes are on the arrogant, that you may bring them down." The word that comes to the preacher is peace.
• In the Old Testament, peace is called shalom. We think of the absence of war or quarrels. Biblical shalom has a richer meaning.
• Shalom is like a circle without distortion. From the center, every point on the edge is the same distance away. No one is alone at the top, no one is alone at the bottom. No one is cherished while another is forgotten.
• "The world God desires is a world without dips or bumps."

3. The Distortions of the World and of Our Hearts

• Reality is not so simple. When you stand in line, age and titles do not matter. Outside, we quickly draw lines between important people and everyone else.
• There are those who have and those who have nothing, those with power and those without, those who can raise their voice and those who cannot, those who get ahead and those who are always put off until later. That is not shalom.
• These distortions are also close to home: in the family, at work, at school, in the neighborhood, people are left aside.
• They are in our hearts: not being understood by one's family, an illness that drags on, having no one to talk to about it. Our own lives are not perfect circles either. We compare ourselves, we lose heart, or we think we are superior. We think we are worthless, or that we alone are right.
• In the world and in each of us there are hollowed-out places, wounded places, things we do not want to remember. David too.

4. God Stands at the Bottom of the Distortion

• Becoming king did not smooth out David's life. He knew great successes and great failures. That is exactly why he knew that God does not leave distortions as they are.
• God does not push down the one who is already low. He does not wound the one who is already wounded. He sits down beside the one who suffers and wants to lift him up. The proud he leads to see their own pride. In this way, little by little, he brings the distorted world back to its original shape, the perfect circle.
• "Peace is not a quiet state where nothing happens. Peace is a world that does not pretend not to see someone who is crying." Shalom is God's dynamic action that heals the wounds of the world, straightens distortions, and restores relationships.
• In the diagram shown during the service, a cross stands at the deepest point of the hollow. God does not give orders from above; he comes from below.
• Jesus was not born in a palace but laid in a manger (Luke 2:7). He did not choose to seize power. He entered in among those who suffer and, in the end, was nailed to a cross. God knows the deepest suffering because he stood in it himself.
• So to seek God, you do not need to look only upward. We want to look strong, to act as if we had not failed, as if we were not hurt. "I'm fine," when we are not. "I'm okay, it doesn't affect me." We force it. God's light does not enter where we are strong, but where we are weak, wounded, where we need help and cannot tell anyone.
• You do not have to hide your weakness. You can acknowledge it before God with confidence, because it is in that weakness that his strength is at work.

5. A Shield for You and for Your Neighbor

• Verse 31: Yahweh "is a shield to all those who take refuge in him."
• Even when we acknowledge our weakness, being hurt is frightening. Being rejected is frightening. Failing is frightening. So we protect ourselves: we build walls, we put on armor, we try to look strong.
• The text does not say, "Be brave, be strong." It says that God becomes our shield. The Bible often compares God to a shield. A shield protects from flying arrows and from the sword coming down.
• The ancient shield had another role. Soldiers stood in a line, side by side. Half of each shield protected the neighbor. A lone shield leaves gaps; shields held close together form a great protection. What cannot be protected alone is protected when we are together.
• The preacher sees in this a picture of the church: one half of the shield for yourself, the other for your neighbor. "The church is not a gathering of perfect people. The church is a gathering of people who seek to be a shield for one another," including for those outside the church.
• God protects us, and he calls us in turn to protect someone: the wounded person, the lonely person, the excluded person. To stand beside the one who cannot raise their voice, to invite those outside to come in. That too is shalom work.
• God is not only "my" shield. The verse says "all those who take refuge in him." Neither nationality, nor gender, nor past failures, nor being a Christian or not, nor the strength or weakness of one's faith changes this.

6. What David Understood at the End of His Life

• David sang this song as his life drew near its end. What he did not understand when he was young, he understood with the years. He probably realized only afterward that he had been protected.
• His life had peaks and valleys, victories and failures. Looking back, he saw that at every moment God had been his shield.
• For us too, the arrows will keep flying: old age, illness, worry, failure. Difficulties will not disappear, nor will sadness. "But there is one important thing: we have a shield." The presence of this shield strengthens us and becomes our hope.
• You have the right to be afraid, to acknowledge your weakness, to ask for help, because God is down below. And you can, with confidence, take a step to protect someone, because the shield is not made for you alone.
• "The Bible does not command us to become stronger. It says: you have a shield." God is with those who are in weakness; he lifts them up, protects them, and leads all people toward shalom. With God as your shield, and being someone's shield, walk toward shalom. You do not walk alone.
• After a time of meditation and prayer, the church sings "As the Deer." For the preacher, this well-known song is the Word of the day itself: "You are my shield, you are my strength, you are my hope, I lift my eyes to the Lord."

Key Takeaways

• Shalom is not the absence of conflict: it is a world where no one is forgotten, and God's action that straightens what is distorted.
• God does not command from above. He stands at the bottom of our hollows, where the cross stands.
• You do not have to hide your weakness: God's light enters where you are wounded.
• God is a shield to all who take refuge in him, and half of your shield is for your neighbor.
• Trials do not disappear, but you have a shield, and you do not walk alone.
