Old school thinking says, "God, you take care of my family and I will take care of your church." Lots and lots of ministers went through life following this philosophy. Unfortunately many of them laid their families down on the altar of "the church".
I believe that God wants us first and foremost to be the shepherd of our own homes. What kind of kids pastor can I be if my own kids grow up resenting church and God because I couldn't keep my priorities in line with God's word.
I as a Kid's Pastor have to make sure that my relationship with my wife and kids is where it needs to be before I can even begin to worry about the church. To learn what the Bible says is expected of a person in leadership with regards to his/her family, just check out 1 Timothy 3. Pretty powerful stuff.
God help me to make sure my kids and my wife know that I love them.
