Matthew 19:28

And Jesus said unto them
To all the disciples whom Peter represented;

verily I say unto you:
the thing being something very considerable, and of great moment, Christ uses the asseveration he sometimes does in such cases:

that ye which have followed me.
Christ does not deny that they had forsaken all for his sake, nor does he despise it, because it was but little they left, though he does not repeat it; but only takes notice of their following him, which, including their faith in him, their profession of him, and subjection to him, was a much greater action, and of more importance that the other, and therefore is only mentioned, and which our Lord confirms:

in the regeneration.
This clause is so placed, that it may be read in connection with the preceding words, and be understood of the disciples following Christ in the regeneration; meaning, not the grace of regeneration, in which they could not be said, with propriety, to follow Christ; and one of them was never a partaker of it: but the new state of things, in the church of God, which was foretold, and is called the time of reformation, or setting all things right, which began upon the sealing up the law, and the prophets, and the ministry of John the Baptist, and of Christ; who both, when they began to preach, declared, that this time, which they call the kingdom of heaven, was at hand, just ushering in. Now the twelve apostles followed Christ herein: they believed, and professed him to be the Messiah; they received, what the Jews called, his new doctrine, and preached it to others; they submitted to the new ordinance of baptism, and followed Christ, and attended him wherever he went, working miracles, preaching the Gospel, and reforming the minds and manners of men. Now this new dispensation is called the regeneration, and which more manifestly took place after our Lord's resurrection, and ascension, and the pouring down of the Spirit; wherefore the phrase may be connected with the following words,

when the Son of man shall sit in the throne of his glory in the
regeneration;
not in the resurrection of the dead, or at the last judgment, but in this new state of things, which now began to appear with another face: for the apostles having a new commission to preach the Gospel to all the world; and being endued with power from on high for such service, in a short time went every where preaching the word, with great success. Gentiles were converted, as well as Jews, and both brought into a Gospel church state; the ceremonies of the old law being abolished, were disused; and the ordinances of baptism, and the Lord's supper, every where practised; old things passed away, and all things became new: agreeably to this the Syriac version renders the phrase, (atdx amleb) , "in the new world"; and so the Persic. The Arabic reads it, "in the generation", or "age to come"; which the Jews so often call the world, or age to come, the kingdom of the Messiah, the Gospel dispensation.

When the Son of man shall sit in the throne of his glory,
or glorious throne; as he did when he ascended into heaven, and sat down at the right hand of God; and was then exalted as a prince, and made, or declared to be Lord and Christ; and was crowned in human nature, with honour, and glory, and angels, principalities, and powers, made subject to him:

ye also shall sit upon twelve thrones:
for though Judas fell from his apostleship, yet Matthias was chosen in his room, and took his place, and made up the number twelve; a metaphorical phrase, setting forth the honour, dignity, and authority of their office and ministry, by which they should be

judging the twelve tribes of Israel;
doctrinally and practically; by charging them with the sin of crucifying Christ, condemning them for their unbelief, and rejection of him, denouncing the wrath of God, and the heaviest judgments that should fall upon them, as a nation, for their sin; and by turning from them to the Gentiles, under which judgment they continue to this day. So the doctors among the Jews are represented as sitting and judging others: of "the potters", in ( 1 Chronicles 4:23 ) they say ^F12,

``these are the disciples of the law, or the lawyers, for whose sake the world is created, (anyd le Nybtyd) "who sit in judgment", and establish the world; and build, and perfect the ruins of the house of Israel.''
