Giving money to the youngest son did not teach him the important lessons about discipleship and hard work. Then, when the younger son showed up at his father's house again after squandering the money, he showed no anger or disappointment. He was welcomed home with a party. This taught the young son that there are no consequences for your actions. Then finally, the father showed appreciation for all his hard work and gave him the money instead. Which would then also teach the younger ones that you have to work to be rewarded. It seems that the youngest son was just like his father. The father was willing to throw away his son's money, so the son was just willing to throw it all away
