 It's not too late. God's not done with you as a parent, influencing the lives of your kids, speaking the name of Christ, seeing your life transformed by the gospel day in and day out, admitting to your faults and your fallacies and your failures in the presence of them and God, helping them unite their hearts to what is true and real and genuine and most effective and most powerful, which is the person of Christ, made known to us by the power of the Spirit. So don't quit just yet. We pray for our kids intellectually.
