After a generation of watching many parents, Christian and non-Christian alike, raise their children in "value free" environments (which is impossible), there is a vast desire amongst young Christian parents to raise their children in the love and nurture of Jesus Christ.
As this movement picks up steam, the great resources of Scripture and Christian tradition, informed by Scripture, are coming to the fore.
They are seeing the clear mandate in Scripture to nurture their children in the truths of God's Word (i.e. Deut. 6 and Eph. 6). They are also seeing that throughout the history of the Church, truth has flourished under such a mandate and withered when that mandate was neglected. Augustine, with much of the early Church, considered the practice vital the health of the Church. The Reformers considered catechizing in particular to be a bulwark for truth against Rome and apostasy. In response, Rome began an extensive program of catechizing as well in order to counter the Reformation.
In the twentieth century, Christian nurture declined with the rise of the experience and decline of the mind. It also was a much less exciting quest than that of cultural renewal or evangelistic crusades. But even with the demise of Christian nurture and the subsequent decline of the Church, there were a million sparks of hope, found in the tongues of babes in Christ, who could tell despairing adults that our purpose in life is to "glorify God and enjoy Him forever," and we can learn how to do this through "the Scriptures of the Old and New Testaments" that "teach us what man is to believe concerning God and what duties God requires of man."
Here are several (life-consuming) ways in which we can provide Christian nurture, while recognizing that it is God who grants salvation, often through, but never because of these human means:
1) Catechizing. We know that it is the Scriptures that make us "wise unto salvation" (2 Tim. 3:15), but how are we to share them with our children? The most important way is to teach our children the basic truths of Scripture through the Westminster Shorter Catechism and its younger equivalent, the Children's Catechism. These catechisms provide a map of God's Word so that a child can successfully navigate it to their great profit, know more concretely what they believe, and be able to better articulate what they believe (2 Pet. 3:15).
2) Knowing the Big Picture. Our children belong to Christ. They are part of His covenant people (Gen. 17; Acts 2). The promises belong to them. What this means is that teaching doesn't start with their "conversion" or profession of faith. It begins when God baptizes them and welcomes them into the family. From that point on, parents and the Church bear responsibility to feed them with the truths with which God has signed and sealed them. A child's baptism and subsequent teaching stands together as a witness, either guiding them to own the Savior who marked them with His grace, or testifying against them in their rebellion.
Though he didn't believe, the great author, Robert Louis Stevenson, even in his dying days, reveled in the majesty of the first question and answer of the WSC: What is the chief end of man? To glorify God and enjoy Him forever. Stevenson said that such a statement strikes at "the very roots of life."
3) A Christ-Centered Curriculum. Whether at home or in the Sunday School class, the choice of materials used to instruct our children is vital. For many years, books and flannel boards were used almost exclusively to tell children to be "do bees" not "don't bees." They heard stories from the Bible in order to "bee good" and "bee courageous," etc. With the Reformed resurgence of recent years, and the renewal of Christ-centered preaching and teaching, the landscape has dramatically changed. You can buy wonderful children's Bibles and Christ-centered stories written by Sally Lloyd-Jones and Carine McKenzie, as well as tremendous Sunday School materials produced by Great Commission Publications.
4) Share the Burden. Christ's mandate to care for His lambs extends to parents as the primary teachers (Eph. 6), under the oversight of the elders (Heb. 13), who are commissioned by Christ to teach His people (Matt. 28). Fathers, in particular, are held to account for their shepherding of their family (Eph. 6). This means we all share the burden of responsibility, which we subsequently lay on the shoulders of Christ, who bore our burdens for us.
Parents must seek to daily instruct their children in the truths of the Gospel, while also modeling the profound effect of those truths. Children won't believe their parents concerning the beauty of God's love for sinners in Christ if they don't see their parents relishing that fact. "Do what I say, not what I do" is profoundly unbiblical. We must strive to life in accordance with our profession, especially before the eyes of our children.
The whole body of believers raised their hands at the child's baptism, committing to assist the parents in the grand and glorious task of Christian nurture. This means that we must all be encouraging each other in this task. Some fellow believers will do this in the role of Sunday School teachers. Others will do this by simple encouragement, while others will model this when children come over to their homes to play.
The elders must hold parents accountable, and encourage them, in the task of Christian nurture. They are responsible for spearheading the Church-based portion of the teaching/nurture of youth, and for occasionally examining children individually to test their progress. They also must visit with parents to encourage and pray with them. Elders and parents desperately need one another in this task, and will have a hard time making any headway without the help of the other.
This task of Christian (or covenant) nurture is incredibly vital, yet incredibly daunting. That probably explains part of its decline as well. As I have been reading Rediscovering Catechism by Donald Van Dyken and taking a class on this subject over the last couple of months, I have found myself incredibly intimidated by the task in front of me. We don't even have consistent morning devotions around the breakfast table!
But I (and you) will continue to grow with the knowledge of this promise given by Christ, alongside His great commission to teach: "And, lo, I am with you until the very end of the age" (Matt. 28). Christ doesn't abandon us to feed and care for His lambs. He is their Shepherd and will guide them in paths of righteousness for His name's sake. And He works in us through the guidance of His Word and power of His Spirit, to this end.
Remember, when God has lead His people through the Red Sea, the children didn't pass through because they were carried on the backs of their parents. They crossed through because God parted the waters of judgment and granted them safe passage into the realm of life. It is important to hold a child's hand through the parted waters until they know the way on their own (which they learn through the nurture above), but it was Christ whose body and blood parted those waters. Don't forget that. He is with you until the very end of the age.
