We are told that there are angels there protecting the young and innocent in the faith, and those who make them stumble are the ones accursed. Some do this because they believe that they are more powerful than those hyper-intelligent demonic beings that consist of the spirit of this world. and rejoice in despoiling all beauty, denying all truth, and removing if not faith, innocence.
These people generally are found towards the top of hierarchies: they are archbishops, moderators, presidents... if not the church then the academy or parliament.
So Christ pleads with such to let their power go and their status. he uses hyperbole: he shreds their pretensions to leadership, status and power. For he does not want any man to be left un-shriven, unsaved, and on that nicely paved and smooth road to perdition.
18 At that time the disciples came to Jesus and said, “Who then is greatest in the kingdom of heaven?” 2 And He called a child to Himself and set him before them, 3 and said, “Truly I say to you, unless you are converted and become like children, you will not enter the kingdom of heaven. 4 Whoever then humbles himself as this child, he is the greatest in the kingdom of heaven. 5 And whoever receives one such child in My name receives Me; 6 but whoever causes one of these little ones who believe in Me to stumble, it would be better for him to have a heavy millstone hung around his neck, and to be drowned in the depth of the sea.
7 “Woe to the world because of its stumbling blocks! For it is inevitable that stumbling blocks come; but woe to that man through whom the stumbling block comes!
8 “If your hand or your foot causes you to stumble, cut it off and throw it from you; it is better for you to enter life crippled or lame, than to have two hands or two feet and be cast into the eternal fire. 9 If your eye causes you to stumble, pluck it out and throw it from you. It is better for you to enter life with one eye, than to have two eyes and be cast into the fiery hell.
10 “See that you do not despise one of these little ones, for I say to you that their angels in heaven continually see the face of My Father who is in heaven. 11 For the Son of Man has come to save that which was lost.
12 “What do you think? If any man has a hundred sheep, and one of them has gone astray, does he not leave the ninety-nine on the mountains and go and search for the one that is straying? 13 If it turns out that he finds it, truly I say to you, he rejoices over it more than over the ninety-nine which have not gone astray. 14 So it is not the will of your Father who is in heaven that one of these little ones perish.
