25:46 And these shall go away into everlasting punishment: but the righteous into life eternal. We shall not enter into the discussions that have arisen over this controverted passage. These things are certain: (1) A separation between the righteous and the wicked takes place at judgment. (2) The righteous inherit the kingdom; the wicked depart into everlasting fire. (3) The state of the righteous is life eternal; the state of the wicked is everlasting punishment. (4) The duration of these two states is the same, exactly the same Greek word being used in each case ( aionios ). Then if the state of punishment has an end, so has the life.
25:46 And these shall go away into everlasting punishment, but the righteous into life everlasting - Either therefore the punishment is strictly eternal, or the reward is not: the very same expression being applied to the former as to the latter. The Judge will speak first to the righteous, in the audience of the wicked. The wicked shall then go away into everlasting fire, in the view of the righteous. Thus the damned shall see nothing of the everlasting life; but the just will see the punishment of the ungodly. It is not only particularly observable here, That the punishment lasts as long as the reward; but, That this punishment is so far from ceasing at the end of the world, that it does not begin till then.
25:31-46 This is a description of the last judgment. It is as an explanation of the former parables. There is a judgment to come, in which every man shall be sentenced to a state of everlasting happiness, or misery. Christ shall come, not only in the glory of his Father, but in his own glory, as Mediator. The wicked and godly here dwell together, in the same cities, churches, families, and are not always to be known the one from the other; such are the weaknesses of saints, such the hypocrisies of sinners; and death takes both: but in that day they will be parted for ever. Jesus Christ is the great Shepherd; he will shortly distinguish between those that are his, and those that are not. All other distinctions will be done away; but the great one between saints and sinners, holy and unholy, will remain for ever. The happiness the saints shall possess is very great. It is a kingdom; the most valuable possession on earth; yet this is but a faint resemblance of the blessed state of the saints in heaven. It is a kingdom prepared. The Father provided it for them in the greatness of his wisdom and power; the Son purchased it for them; and the blessed Spirit, in preparing them for the kingdom, is preparing it for them. It is prepared for them: it is in all points adapted to the new nature of a sanctified soul. It is prepared from the foundation of the world. This happiness was for the saints, and they for it, from all eternity. They shall come and inherit it. What we inherit is not got by ourselves. It is God that makes heirs of heaven. We are not to suppose that acts of bounty will entitle to eternal happiness. Good works done for God's sake, through Jesus Christ, are here noticed as marking the character of believers made holy by the Spirit of Christ, and as the effects of grace bestowed on those who do them. The wicked in this world were often called to come to Christ for life and rest, but they turned from his calls; and justly are those bid to depart from Christ, that would not come to him. Condemned sinners will in vain offer excuses. The punishment of the wicked will be an everlasting punishment; their state cannot be altered. Thus life and death, good and evil, the blessing and the curse, are set before us, that we may choose our way, and as our way so shall our end be.
