Homeschooling is not a saving grace. It's not a guarantee that our children will grow up to love God and hate sin. Enrolling them in a Christian school isn't the solution either.
We bring up children in the Lord through the Word and Sacrament. And we cannot have those without the visible church! What they see and hear in church must be echoed in the home. So our role and responsibility as parents acting as prophets, priests, and kings to our children is crucial.* God help us do it good and do it proper! And then we pray hard that the Spirit of God work mightily in their hearts as we subject them (and ourselves) to the means of grace — Word, sacrament, and prayer (WSC 88) — corporately in the covenant community and consistently in our homes.
Spirit-wrought discipleship springs from a sanctified commitment to the ordinary means of grace. Not homeschooling. Not Sunday School either. God can use those things. But God has ordained to bless the means of grace. Believe in that promise and fight for your children to hear the words of Christ every Lord's Day! And find a church that welcomes them just as Jesus welcomes little children.
