Albert Barnes Commentary Luke 22:28

"But ye are they that have continued with me in my temptations;" — Luke 22:28 (ASV)

My temptations. My trials, my humiliations, and my assaults from the power of Satan and a wicked world.

And I appoint to you a kingdom. He assures them here that they would have a kingdom—their expectations would be realized. They had continued with Him; they had seen how He had lived, and to what trials He had been subjected; they had all along expected a kingdom, and He assures them that they would not be disappointed.

As my Father, and so forth. They had seen how God had appointed a kingdom to Him. It was not with pomp and splendor and external glory, but it was in poverty, want, persecution, and trial. So He would appoint a kingdom to them. They would surely possess it; but it would not be with external splendor, but by poverty and toil.

The original word appoint has the force of a covenant or compact and means that it would surely or certainly be done, or that He pledged Himself to do it. All Christians must enter the kingdom of heaven in the same way as their Lord—through much tribulation. But though it must be, as it was with Him, by many tears and sorrows, yet they will surely reach the place of their rest and the reward of heaven, for it is secured to them by the covenant pledge and faithfulness of their Lord and King.
