Scott Thomas has a brilliant post on raising children today. I thought his advice on discipline was especially great:
"The goal of discipline is to teach that God has standards of obedience and that He is the One who has absolute authority in our lives. Teach the gospel clearly in your discipline:
a) Identity as a child belonging to a family, b) sin separates, c) sin has consequences, d) confession, e) repentance, f) reconciliation. Share this story of the Redeemer every time you exercise discipline. "
