This is the one thing which the Apostle offers to the Christian brethren for their support and consolation against the scoffers. And the knowledge is mighty for those who grasp it. It helps them to cast themselves securely upon the almighty arms, convinced that God's working is not to be estimated according to man's days and years, but is certain in its effect. One generation passeth away, and another cometh; but death, they learn, does not take men out of the knowledge or the hand of God, be it for mercy they are reserved, or for judgement. God does not defer His action because He lacks power to perform, neither does He tarry because He is unmindful of His servants or insensible to what they endure. Such thoughts can minister to the faithful abundant consolation, and this was the desire of the Apostle. But they raise for all time large questions which can find no answer here, questions concerning the lot of those who pass from this brief day of life into the eternal world and have not known God's will, that they might do it; questions concerning a discipline which may yet be reserved for some who have not bent themselves to it here, perhaps from want of light; questions of how far hope may extend itself beyond the veil which divides this world from the next. Such questions rise within many earnest souls, often rather for the sake of others than themselves; but God has vouchsafed us no answer, lest men should wax presumptuous. _The Lord is not slack concerning His promise, as some count slackness._ Many things conspire to make the doings of men to tarry. At one time pledges are given beyond what foresight would warrant; and when the day of performance arrives, they are forced to plead that events have falsified their expectation, and they cannot do the things that they would. Again, men, with the most earnest zeal, attempt a work beyond their powers, and of necessity have to delay the fulfilment of their promises; while some are taken away untimely from the midst of their fellows, ere life has enabled them to achieve what they counted on once as certain. Want of knowledge, of time, and of power is the heritage of the sons of men; and therewith conspires not seldom a change of mind and consequent want of will. But He with whom is no variableness, the omnipotent, omniscient, eternal Lord of all, is subject to no hindrance. Whether events appear to men to linger or to be sudden, all move under the control of the same unchanging will. He is not slack, as men are slack, either to rescue the righteous or to punish the ungodly. Of this the son of Sirach spake: "The Lord will not be slack, neither will the Almighty be patient, ... till He have taken away the multitude of the proud and broken the sceptre of the unrighteous, ... till He have judged the cause of His people and made them to rejoice in His mercy" (Ecclus. xxxv. 18).
