John Wesley on Matthew 19:28

In the renovation - In the final renovation of all things: Ye shall sit - In the beginning of the judgment they shall stand, 2Cor 5:10. Then being absolved, they shall sit with the Judge, 1Cor 6:2: On twelve thrones - So our Lord promised, without expressing any condition: yet as absolute as the words are, it is certain there is a condition implied, as in many scriptures, where none is expressed. In consequence of this, those twelve did not sit on those twelve thrones: for the throne of Judas another took, so that he never sat thereon.
