Jesus often uses the analogy of children when He is showing the difference that exists between His followers and everyone else.  Children are the great dependent class of humanity.  They would be utterly doomed without parents or guardians to feed, clothe, and train them. This hearkens back to the first beatitude that Jesus taught in the gospel of Matthew, “Blessed are the poor in spirit” (5:3).  Scripture makes it clear it is impossible for the wisdom of this world to move us toward God (I Corinthians 1:18-31; 3:18-21).  Like children, we must be completely aware of our need to be shown the way by God Himself.  This affirms the teaching of Jesus who declares we must be like children to come to Him (Matthew 18:3).
