Why do we have Sunday School or Bible School?
Proverbs tells us to train up a child in the way he should go, that when he grows old he will depart away from it.
Psalms 119 talks about the law and love for God's precepts.
Matt. 28 tells us to go make disciples.
2 Timothy 3:16 says: "All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness."
Why Bible School? It gives opportunity to learn God's Word and apply it to our lives. Why not?!
