(1.) They will rejoice in seeing the justice of God glorified in the sufferings of the damned. The misery of the damned, dreadful as it is, is but what justice requires. They in heaven will see and know it much more clearly, than any of us do here. They will see how perfectly just and righteous their punishment is, and therefore how properly inflicted by the supreme Governor of the world. They will greatly rejoice to see justice take place, to see that all the sin and wickedness that have been committed in the world is remembered of God, and has its due punishment. The sight of this strict and immutable justice of God will render him amiable and adorable in their eyes. They will rejoice when they see him who is their Father and eternal portion so glorious in his justice.
Then there will be no remaining difficulties about the justice of God, about the absolute decrees of God, or any thing pertaining to the dispensations of God towards men. But divine justice in the destruction of the wicked will then appear as light without darkness, and will shine as the sun without clouds, and on this account will they sing joyful songs of praise to God, as we see the saints and angels do, when God pours the vials of his wrath upon antichrist; Rev. 16:57 They sing joyfully to God on this account, that true and righteous are his judgments, Rev. 19:16. They seeing God so strictly just will make them value his love the more. Mercy and grace are more valuable on this account. The more they shall see of the justice of God the more will they prize and rejoice in his love.
(2.) They will rejoice in it, as it will be a glorious manifestation of the power and majesty of God. God will show his own greatness in executing vengeance on ungodly men. This is mentioned as one end of the destruction the ungodly: “What if God, willing to show his wrath, and make his power known, endured with much longsuffering the vessels of wrath fitted to destruction ?” God will hereby show how much he is above his enemies. There are many now in the world, who proudly lift up themselves against God. There are many open opposers of the cause and interest of Christ. “They set their mouth against the heavens, and their tongue walketh through the earth.” Then God will show his glorious power in destroying these enemies.
The power of God is sometimes spoken of as very glorious, as appearing in the temporal destruction of his enemies: Exod. 15:6, “Thy right hand, O Lord, is become glorious in power; thy right hand, O Lord, hath dashed in pieces the enemy.” But how much more glorious will it appear in his triumphing over, and dashing in pieces at once, all his enemies, wicked men and devils together, all his haughty foes! The power of God will gloriously appear in dashing to pieces his enemies as a potter’s vessel. Moses rejoiced and sang when he saw God glorify his power in the destruction of Pharaoh and his host at the Red Sea. But how much more will the saints in glory rejoice when they shall see God gloriously triumphing over all his enemies in their eternal ruin! Then it will appear how dreadful God is, and how dreadful a thing it is to disobey and condemn him. It is often mentioned as a part of the glory of God, that he is a terrible God. To see the majesty, and greatness, and terribleness of God, appearing in the destruction of his enemies, will cause the saints to rejoice; and when they shall see how great and terrible a being God is, how will they prize his favor! How will they rejoice that they are the objects of his love! How will they praise him the more joyfully, that he should choose them to be his children, and to live in the enjoyment of him!
It will occasion rejoicing in them, as they will have the greater sense their own happiness, by seeing the contrary misery. It is the nature of pleasure and pain, of happiness and misery, greatly to heighten the sense of each other. Thus the seeing of the happiness of others tends to make men more sensible of their own calamities; and the seeing of the calamities of others tends to heighten the sense of our own enjoyments.
When the saints in glory, therefore, shall see the doleful state of the damned, how will this heighten their sense of the blessedness of their own state, so exceedingly different from it! When they shall see how miserable others of their fellowcreatures are, who were naturally in the same circumstances with themselves; when they shall see the smoke of their torment, and the raging of the flames of their burning, and hear their dolorous shrieks and cries, and consider that they in the mean time are in the most blissful state, and shall surely be in it to all eternity ; how will they rejoice!
This will give them a joyful sense of the grace and love of God to them; because hereby they will see how great a benefit they have by it. When they, shall see the dreadful miseries of the damned, and consider that they deserved, the same misery, and that it was sovereign grace, and nothing else, which made them so much to differ from the damned, that, if it had not been for that, they would have been in the same condition; but that God from all eternity was pleased to set his love upon them, that Christ hath laid down his life for them, and hath made them thus gloriously happy forever, O how will they admire that dying love of Christ, which has redeemed them from so great a misery, and purchased for them so great happiness, and has so distinguished them from others of their fellowcreatures! How joyfully will they sing to God and the Lamb, when they behold this!
