As a parent I have no greater responsibility than the spiritual health of my child. Period. That is my greatest role in life, to fulfill the Great Commission in the life of each of my children. That is not to say that they come before my relationship with God, but that they are the immediate recipients of the overflow of my relationship with God(aside from my spouse). This is true for any parent. Whether you stay at home with them all day, or pastor a church of 50,000 people, the spiritual health of your children is your primary mission field.
