(3.) He must count upon no other than that, as long as the world stands, there will still be in it such a mixture as now we see there is of good and bad, v. 10. We long to see all wheat and no tares in God's field, all corn and no chaff in God's floor; but it will not be till the time of ingathering, till the winnowing day, comes; both must grow together until the harvest. As it has been, so it is, and will be, The wicked shall do wickedly, but the wise shall understand. In this, as in other things, St. John's Revelation closes as Daniel did. Rev. xxii. 11, He that is filthy, let him be filthy still; and he that is holy, let him be holy still. [1.] There is no remedy but that wicked people will do wickedly; and such people there are and will be in the world to the end of time. So said the proverb of the ancients, Wickedness proceeds from the wicked (1 Sam. xxiv. 13); and the observation of the moderns says the same. Bad men will do bad things; and a corrupt tree will never bring forth good fruit. Do men gather grapes of thorns, or bring forth good things from an evil treasure in the heart? No; wicked practices are the natural products of wicked principles and dispositions. Marvel not at the matter then, Eccl. v. 8. We are told, before, that the wicked will do wickedly; we can expect no better from them: but, which is worse, none of the wicked shall understand. This is either, First, A part of their sin. They will not understand; they shut their eyes against the light, and none so blind as those that will not see. Therefore they are wicked because they will not understand. If they did but rightly know the truths of God, they would readily obey the laws of God, Ps. lxxxii. 5. Wilful sin is the effect of wilful ignorance; they will not understand because they are wicked; they hate the light, and come not to the light, because their deeds are evil, John iii. 19. Or, Secondly, It is a part of their punishment; they will do wickedly, and therefore God has given them up to blindness of mind, and has said concerning them, They shall not understand, nor be converted and healed, Matt. xiii. 14, 15. God will not give them eyes to see, because they will do wickedly, Deut. xxix. 4. [2.] Yet, bad as the world is, God will secure to himself a remnant of good people in it; still there shall be some, there shall be many, to whom the providences and ordinances of God shall be a savour of life unto life, while to others they are a savour of death unto death. First, the providences of God shall do them good: Many shall be purified, and made white, and tried, by their troubles (compare ch. xi. 35), by the same troubles which will but stir up the corruptions of the wicked and make them do more wickedly. Note, The afflictions of good people are designed for their trial; but by these trials they are purified and made white, their corruptions are purged out, their graces are brightened, and made both more vigorous and more conspicuous, and are found to praise, and honour, and glory, 1 Pet. i. 7. To those who are themselves sanctified and good every event is sanctified, and works for good, and helps to make them better. Secondly, The word of God shall do them good. When the wicked understand not, but stumble at the word, the wise shall understand. Those who are wise in practice shall understand doctrine; those who are influenced and governed by the divine law and love shall be illuminated with a divine light. For if any man will do his will he shall know the truth, John vii. 17. Give instruction to a wise man, and he will be yet wiser.
