It’s amazing that the disciples argued from time to time about who would be the greatest in the Kingdom of God. They should have learned from their association with Jesus that humility is more important than honor. True consecration is all about service and not about exaltation. So, to drive this point home Jesus used the example of a child, explaining to the disciples that true greatness is in how we treat the weak and needy and humble people whom God puts in our pathway each day.
(Mark 9:33-37) 33 They came to Capernaum. When he was in the house, he asked them, “What were you arguing about on the road?” 34 But they kept quiet because on the way they had argued about who was the greatest. 35 Sitting down, Jesus called the Twelve and said, “Anyone who wants to be first must be the very last, and the servant of all.”
36 He took a little child whom he placed among them. Taking the child in his arms, he said to them, 37 “Whoever welcomes one of these little children in my name welcomes me; and whoever welcomes me does not welcome me but the one who sent me.”
