(3) Remember therefore how (or, after what sort) thou hast received and heard (or, didst hear--the tense changes).--Remembering that the words are addressed primarily to the angel himself, the change of tense may have been designed to point him back to some particular period of his life, such as the time when he was set apart to his ministerial work. The further expectation is to hold fast, or keep--i.e., as an abiding habit. It has been noticed that this counsel is identical with that given to Timothy to "keep the good thing which had been committed to his charge" (2Timothy 1:14; comp. also 2Timothy 2:2). "Repent" is the closing word; combined with the exhortation to hold fast, it reminds us that formal tenacity of truth and a fruitless inactive regret are alike useless. There must be the sorrow for the past, and a sorrow which shows itself in action--a repentance whereby sin is forsaken. (Comp. Revelation 2:5; Revelation 2:21.)

If therefore thou shalt not watch.--Better, If thou shalt not watch (or, have been awake), I will come (omit "on thee") as a thief, and thou shalt not know what hour I will come upon thee. The warning is an echo from the Gospels (Matthew 24:42-43; Luke 12:39-40). The coming of Christ to judge His Church would be in an hour unlooked for. What kind of hour He would so come was' unknown; the sound of His approaching footsteps unheard. Shod with wool, according to the ancient proverb, stealthily as a thief, the Judge would be at the door. Yet they could not plead that they had been in darkness (1Thessalonians 5:4).

Verse 3. - Remember therefore how thou hast received and didst hear (comp. Revelation 2:5). Like the Ephesians, the Sardians are reminded of the better condition from which they have receded. They are of those "who, when they have heard the Word, straightway receive it with joy; and they have no root in themselves, but endure for a while" (Mark 4:16, 17). The "how," as is shown by the verbs "receive" and "hear," refers to the readiness with which they accepted the gospel, rather than to the power with which it was preached to them. The tenses are instructive: the aorist applies to the hearing at some definite period in their history; the perfect implies the permanent result of the act of reception. Keep and repent. Keep what thou didst hear. "Keep" is better than "hold fast," to mark the difference between τηρεῖν (Revelation 1:3; Revelation 2:26; Revelation 3:3, 8, 10, etc.), and κρατεῖν (Revelation 2:1, 13, 14, 15, 25; Revelation 3:11, etc.). Here again the tenses should be noted: the present imperative indicates that they are to continue to keep; the aorist, that they are to repent once for all. We have a similar combination of tenses in" Take these things hence at once; continue to refrain from making my Father's house a house of merchandise" (John 2:16; comp. John 5:8, 11; Acts 12:8; 1 Corinthians 15:34). "Remember" here and in Revelation 2:5 is with equal fitness the present imperative: "continue to remember." I will come as a thief. The "on thee" after "come," though well supported, is probably not genuine. Wherever this figure is used in the New Testament of the coming of Christ, the word used is κλέπτης, "a thief," and not ληστής, a "robber" or "bandit." This shows, what is also plain from the context, that secrecy, not violence, is the point of the similitude (comp. Revelation 16:15; Matthew 24:43; Luke 12:39; 1 Thessalonians 5:2; 2 Peter 3:10). Thou shalt not know what hour; literally, thou shalt in no wise come to know during what kind of an hour. The negative is the strongest form, οὐ μή (Revelation 2:11; Revelation 3:5, 12). The verb is γινώσκειν, which implies acquisition of knowledge (Revelation 2:23, 24; Revelation 3:9). The pronoun is ποῖος (John 10:32; John 12:33; John 18:32; John 21:19; and especially Matthew 24:42; Luke 12:39); and "hour" is in the accusative (John 4:52).

3:1-6. The Lord Jesus is He that hath the Holy Spirit with all his powers, graces, and operations. Hypocrisy, and lamentable decay in religion, are sins charged upon Sardis, by One who knew that church well, and all her works. Outward things appeared well to men, but there was only the form of godliness, not the power; a name to live, not a principle of life. There was great deadness in their souls, and in their services; numbers were wholly hypocrites, others were in a disordered and lifeless state. Our Lord called upon them to be watchful against their enemies, and to be active and earnest in their duties; and to endeavour, in dependence on the grace of the Holy Spirit, to revive and strengthen the faith and spiritual affections of those yet alive to God, though in a declining state. Whenever we are off our watch, we lose ground. Thy works are hollow and empty; prayers are not filled up with holy desires, alms-deeds not filled up with true charity, sabbaths not filled up with suitable devotion of soul to God. There are not inward affections suitable to outward acts and expressions; when the spirit is wanting, the form cannot long remain. In seeking a revival in our own souls, or the souls of others, it is needful to compare what we profess with the manner in which we go on, that we may be humbled and quickened to hold fast that which remains. Christ enforces his counsel with a dreadful threatening if it should be despised. Yet our blessed Lord does not leave this sinful people without some encouragement. He makes honourable mention of the faithful remnant in Sardis, he makes a gracious promise to them. He that overcometh shall be clothed in white raiment; the purity of grace shall be rewarded with the perfect purity of glory. Christ has his book of life, a register of all who shall inherit eternal life; the book of remembrance of all who live to God, and keep up the life and power of godliness in evil times. Christ will bring forward this book of life, and show the names of the faithful, before God, and all the angels, at the great day.Remember, therefore, how thou hast received and heard,.... That is, hast received upon hearing; for hearing goes first, and then receiving: the design of the advice is to put this church in mind of the doctrines of grace she had heard at the beginning of the Reformation, from Luther and others; such as justification by the righteousness of Christ, pardon through his blood, and atonement by his sacrifice, doctrines now almost lost and buried in forgetfulness; wherefore Christ would have her remember these things; how that she heard them with attention, reverence, humility, and without prejudice; and with much affection, so as to approve and love them, believe them, feel the power of them, and taste the goodness in them; and how she received them with all meekness, readiness, and joy, when now they are greatly disliked and rejected by many; very few attend to the doctrines of the Reformation. This is exactly our case:

and hold fast; the above doctrines, though the majority is against them, and learned men despise them, and they are charged with enthusiasm and licentiousness. It looks as if there was danger, as there is, that they would be entirely wrested out of her hands:

and repent: of her deadness, coldness, and indifference to these truths; of her unwatchfulness over them, and imperfection in them; not carrying truth to its fulness and perfection, resting in her first light and knowledge, and even going back from that:

if therefore thou shalt not watch: and preserve truth, and hold fast the form of sound words, and keep to the order, as well as the faith of the Gospel, and constantly attend divine worship, and look for the coming and kingdom of Christ:

I will come on thee as a thief; in the night, and at unawares, unthought of, and unexpected; which must be understood of coming to her in a way of rebuke and chastisement, by bringing some affliction, or suffering some sore distress to fall upon her: the phrase, "on thee", is left out in the Alexandrian copy and in the Ethiopic version:

and thou shalt not know what hour I will come upon thee: which, though applicable to the spiritual coming of Christ in the next church state, and to his second coming in his kingdom and glory, which will be both sudden and unexpected, yet these will be to the joy and comfort of the church; whereas what is here spoken is by way of threatening, and must relate to some severe dispensation on her; and which we might now justly expect, were we not in the unwatchful, unthoughtful, and ignorant situation here described.
