Matthew 24:10

“And then will many stumble (or ‘be entrapped'), and will deliver up one another, and will hate one another.”

Not all will go smoothly, even among His followers. The world will stumble on in its darkness, and some of those who profess to follow Him will also be ensnared by the world, and will stumble, and they will then act vindictively against their one time ‘brethren', delivering them up to the authorities and being filled with hatred against them, following the patterns among the Jews (Matthew 10:17; Matthew 10:21; compare John 16:2). No one knows how to hate better than an apostate, and there is nothing more painful than to be betrayed by those who once professed to be fellow-brethren. But it was something to be expected. We can compare here how Judas' betrayal must have hurt Jesus so deeply. But the disciples are to be prepared for this as well. (This is in contrast with the love that will be established among those who are truly His - John 13:34; John 17:21). Compare here Matthew 10:17; Matthew 10:21; Matthew 10:35. To Jesus this is a necessary part of the battle between truth and falsehood.
