Matthew 24:50

(Verse 50, 51.) The lord of that servant will come on a day when he does not expect him and at an hour he does not know, and he will divide him and place his portion with the hypocrites. There will be weeping and gnashing of teeth. This teaches that they should know when the lord is not expected, then he will come, and it warns the stewards of vigilance and diligence.

(Ep. 199 in fin.) Putting aside this wicked servant, who, there is no doubt, hates his Master's coming, let us set before our eyes these good servants, who anxiously expect their Lord's coming. One looks for His coming sooner, another later, the third confesses his ignorance of the matter. Let us see which is most agreeable to the Gospel. One says, Let us watch and pray, because the Lord will quickly come; another, Let us watch and pray, because this life is short and uncertain, though the Lord's coming may be distant; and the third, Let us watch, because this life is short and uncertain, and we know not the time when the Lord will come. What else does this man say than what we hear the Gospel say, Watch, because ye know not the hour in which the Lord shall come? All indeed, through longing for the kingdom, desire that that should be true which the first thinks, and if it should so come to pass, the second and third would rejoice with him; but if it should not come to pass, it were to be feared that the belief of its supporters might be shaken by the delay, and they might begin to think that the Lord's coming shall be, not remote, but never. He who believes with the second that the Lord's coming is distant will not be shaken in faith, but will receive an unlooked for joy. He who confesses his ignorance which of these is true, wishes for the one, is resigned to the other, but errs in neither, because he neither affirms or denies either.

The Lord of that servant shall come in a day when he looketh not for Him, is to rouse the stewards to watchfulness and carefulness.

Then, as He had fallen upon the mention of the judgment, He directs His discourse to the teachers next, speaking of punishment and honors; and having put first them that do right, He ends with them that continue in sin, making His discourse to close with that which is alarming. Wherefore He first saith this, "Who then is the faithful and wise servant, whom his Lord shall set over His household to give them their meat in theirs due season? Blessed is that servant, whom his Lord when He cometh shall find so doing. Verily I say unto you, that He shall make him ruler over all His goods." Tell me, is this too the language of one who is in ignorance? For if because He said, "neither doth the Son know," thou sayest He is ignorant of it; as He saith, "who then?" what wilt thou say? Wilt thou say He is ignorant of this too? Away with the thought. For not even one of them that are frantic would say this. And yet in the former case one might assign a cause; but here not even this. And what when He said, "Peter, lovest thou me?" asking it, knew He not so much as this? nor when He said, "Where have ye laid Him?" And the Father too will be found to be saying such things. For He Himself likewise saith, "Adam, where art thou?" and, "The cry of Sodom and Gomorrah is waxed great before me. I will go down therefore, and see whether their doings be according to their cry which cometh unto me, and if not, I will know." And elsewhere He saith, "Whether they will hear, whether they will understand." And in the gospel too, "It may be they will reverence my Son:" all which are expressions of ignorance. […]

For in the last days false prophets shall be multiplied, and such as corrupt the word; and the sheep shall be changed into wolves, and love into hatred: for through the abounding of iniquity the love of many shall wax cold. For men shall hate, and persecute, and betray one another. And then shall appear the deceiver of the world, the enemy of the truth, the prince of lies, [2 Thessalonians 2:3-12] whom the Lord Jesus "shall destroy with the spirit of His mouth, who takes away the wicked with His lips; and many shall be offended at Him. But they that endure to the end, the same shall be saved. And then shall appear the sign of the Son of man in heaven;" [Isaiah 11:4; Matthew 24:1-51] and afterwards shall be the voice of a trumpet by the archangel; and in that interval shall be the revival of those that were asleep. And then shall the Lord come, and all His saints with Him, with a great concussion above the clouds, with the angels of His power, [Matthew 16:27] in the throne of His kingdom, to condemn the devil, the deceiver of the world, and to render to every one according to his deeds. "Then shall the wicked go away into everlasting punishment, but the righteous shall go into life eternal," [Matthew 25:46] to inherit those things "which eye has not seen, nor ear heard, nor have entered into the heart of man, such things as God has prepared for them that love Him;" [1 Corinthians 2:9] and they shall rejoice in the kingdom of God, which is in Christ Jesus.
