It is my office to punish sin, and therefore as I know their sins, so I will assuredly punish them. Their feet shall slide; they who now think they stand fast and unmovable, they shall fall into utter destruction. In due time; though not so soon as some may expect it, yet in that time when it shall be most proper and seasonable, when they have filled up the measure of their sins. This due time may be the same with that fulness of time, Galatians 4:4, when Christ came into the world, whom this people by wicked hands crucified and slew, Acts 2:23, for which wrath came upon them to the uttermost, 1 Thessalonians 2:15,16. Is at hand, Heb. is near. So the Scripture oft speaks of those things which are at many hundred years distance, to meet with objections arising in men's minds from the delays of them, and to signify, that though they may be afar off as to our measures of time and expectation of the things, yet in God's account they are near, they are as near as may be; as soon as ever the fit and the full time is come, they come instantly, they are nearer than sinners would have them; when the measure of their sins is once full, the judgment shall not be deferred.
