The need for a vital, trusting, and repentant faith leads us to consider suggestive steps in teaching our children about the sacrament. First, we must pray for ourselves and our children. The Holy Spirit must enliven the spiritually dead heart of anyone who would believe, including the hearts of our children and grandchildren (Eph. 2:1). This reality places us on our knees before a sovereign God. Our prayers should be marked with confidence in our covenant God, though not passionless presumption. The Lord regards children of believing parents as “holy,” as we read in 1 Corinthians 7:14, set apart by God from this world. Thus, we pray not only for them but with them.
Second, we must tell the story of God’s redemption to our younger children in their concrete learning preschool years. In Deuteronomy 6:4–7, we read:
Hear, O Israel: The Lord our God, the Lord is one. You shall love the Lord your God with all your heart and with all your soul and with all your might. And these words that I command you today shall be on your heart. You shall teach them diligently to your children, and shall talk of them when you sit in your house, and when you walk by the way, and when you lie down, and when you rise.
In other words, we take every opportunity to tell the story of God’s grace from Genesis to Revelation. We make sure our children know that Jesus is our Commander. He calms even the Sea of Galilee (Mark 4:35–41). Thus, when He says of the supper, “Do this in remembrance of me,” we observe it in love and obedience (Matt. 26:26; Mark 14:22–24; Luke 22:19). We tell the story of the Passover in Exodus 12 and remind our children—like the children of the exodus—that the blood placed over the door of the Israelites foreshadowed the ultimate covering of protection in Jesus Christ, the Lamb of God, who is our Passover Lamb (1 Cor. 5:7).
Third, as our children mature in the elementary years, so does their capacity for symbolism and conceptual learning. Our Reformed confessions and catechisms continue to prove of great use as outlines for our lessons. Take advantage of communicants classes at church. At home, convey the need to prepare for the meal in examining our lives, repenting daily, and resting in His forgiveness (Westminster Larger Catechism 170–175; Westminster Shorter Catechism 97). Speak of the need for a sober awareness of the Lord’s body given and His blood shed for our sins while also explaining how we eat and drink in joyful union with the body of Christ. Explain how we truly and really commune with our risen Head, Jesus Christ—through His Spirit—as He rules and reigns over all things.
God gives officers of His church solemn responsibilities. Though parents wield the rod of correction, the officers hold the keys of the kingdom, administering church discipline (Matt. 16:19). This is why we teach our children the need for fencing the Lord’s Table—excluding the nonrepentant as unworthy to take the supper (1 Cor. 11:27). Yet herein lies a golden gospel opportunity. While the Lord will not countenance the proud at His table, He beckons the poor in spirit (Matt. 5:3). So we teach them to repent daily and trust Jesus. We remind them that we parents also are wretched sinners apart from Christ. Yet together, by His grace, we shall eat and drink with all of God’s children at the wedding supper of the Lamb forever (Rev. 19:6–9).
