In Mark 6 the writer connects 3 stories about bread that are important for any disciple to learn. In the first, Jesus sends out his disciples in order to heal the sick and cast out demons. As they prepare to depart the first instruction is "don't take any bread." That seems strange as they prepare to travel. As the father of 3 kids, I always make sure we have plenty of snacks in the car before we head out.
Lesson #1: God wants to depend on him for your needs.
Following this we told about John the Baptist being in jail. As he is there, Herod's step-daughter dances for him, pleasing him to the extent that we promises her anything she desires. Like any normal girl she asks for the head of John (just the accessory that anyone would want). John's head is immediately brought to her on a platter. You may wander what is the connection with bread. let me ask you, what is normally served on a platter?
Lesson #2: Sometimes God will ask you to become the bread.
Finally, the disciples are back with Jesus and he has resumed his teaching. The crowds have been following and now they are hungry. Jesus tells the disciples to feed to crowd (remember they have already learned to depend on God for their needs!) They say they cannot, a young boy provides his lunch for 5,000 people and they collect 12 baskets of leftovers.
Lesson #3: Sometimes God provides an overwhelming abundance to your need.
We tend to like lessons 1 and 3, but 2 really throws us.
If John, Jesus's cousin, the New Elijah, the one to prepare for the coming Messiah got this treatment, can we expect it to be any different for us at some point in our lives?
