John Calvin Commentary Luke 22:28

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

You are they who have continued with me. Although Luke appears to relate a different discourse of Christ, and one which was delivered at a different time, yet I have no doubt that it refers to the same time. For it is not a continuous discourse of Christ that is related here, but detached sentences, without any regard to the order of time, as we will shortly have occasion to state.

But Luke uses more words than Matthew, for he declares that, as the apostles had accompanied Christ and had remained steadfastly in his temptations, they would also be partakers of his glory. It is asked, in what sense does Christ call them his temptations?

I think that he means the contests by which God tried him and the apostles together. And he properly used the word temptations; for, from the perspective of human nature, his faith and patience were actually tried.
