‘Then said he unto the disciples, It is impossible but that offences will come: but woe unto him, through whom they come! It were better for him that a millstone were hanged about his neck, and he cast into the sea, than that he should offend one of these little ones’ (Luke 17:1–2). . . .

In the passage from Luke, Jesus warns against stumbling or offending little ones. He attaches one of the most dire warnings in the Bible to this caution (v. 2). Jesus said a lot of things about children that are routinely ignored today, just as the first disciples tended to ignore them.
