Verses 22-25 “22And he said unto the disciples, The days will come, when ye shall desire to see one of the days of the Son of man, and ye shall not see it.
23And they shall say to you, See here; or, see there: go not after them, nor follow them.
24For as the lightning, that lighteneth out of the one part under heaven, shineth unto the other part under heaven; so shall also the Son of man be in his day.
25But first must he suffer many things, and be rejected of this generation.
The coming of Christ in glory to establish His kingdom will be sudden. It will happen quickly, like a lightning bolt. But the disciples would all suffer for the cause of Christ before He returned. Most if not all of them, would be killed for the cause of the gospel. They would long for those peaceful days when they followed Jesus through the hills and valleys of Judea. There have been, and there will yet be, false christs. But Jesus said do not go after those christs. But first things first! Jesus said that first He would have to suffer. He would suffer in the Garden of Gethsemane. He would suffer in the trials after He was arrested. He would suffer when He was beaten. He would suffer on the cross. All of that suffering was for our sin. He paid our sin debt. And He suffered when He was rejected by His own people, the Jews. The word “generation” in verse 25 refers to the Jewish people.
