Mark 8:2 I have compassion for these people; they have already been with me three days and have nothing to eat.
Can you imagine following someone around just to hear them talk about God – and to not bring food with you for the journey...
And if that lasted more than three days! Would you be thinking about going back home and getting some food?
God knew the people had been totally taken in by Jesus’ words, and knew they needed to be fed – He had compassion on them and wanted Jesus to feed them.
Jesus obeyed!
