As parents, we can have all kinds of goals for our children. We want them to be well educated, well behaved, able to succeed, etc. Some goals might be very good, such as being well behaved or church attendance. Some goals might be shallower such as excelling in sports or something else that's not bad in and of itself. But all of the goals we may have for our children must be secondary to them loving God with all their heart, soul, mind, and strength. It’s possible to have well behaved children who have no desire to love God and don’t know Jesus at all.
Westminster Catechism question one sums up the main goal every parent should have for their children: the chief goal of all mankind is to glorify God and enjoy Him forever. In order to achieve this end parents, of course, need to train their children according to the Scripture and model love for God in their own lives. But no matter what we do as parents we must face the reality that we can’t save our children.
No pedigree is automatic to produce children who love God. Reformed, Christian educated or homeschooled, catechized, verse memorizing, (the list can go on and on) children can still grow up not knowing Jesus and having no love for God. This sobering reality means that we as parents are totally dependent on the grace of God for the salvation of our children. So, as important as the previous list is, the most important thing we can do for our kids is pray, approaching the throne of grace on behalf of our children. In the grace of God is the absolute best place to be.
