21 Evil pursueth sinners: but to the righteous good shall be repayed.
1. How unavoidable the destruction of sinners is; the wrath of God pursues them, and all the terrors of that wrath: Evil pursues them closely wherever they go, as the avenger of blood pursued the manslayer, and they have no city of refuge to flee to; they attempt an escape, but in vain. Whom God pursues he is sure to overtake. They may prosper for a while and grow very secure, but their damnation slumbers not, though they do.
2. How indefeasible the happiness of the saints is; the God that cannot lie has engaged that to the righteous good shall be repaid. They shall be abundantly recompensed for all the good they have done, and all the ill they have suffered, in this world; so that, though many have been losers for their righteousness, they shall not be losers by it. Though the recompence do not come quickly, it will come in the day of payment, in the world of retribution; and it will be an abundant recompence.
– Matthew Henry Commentary
