Keep yourselves from idols Though this be a separate sentence, yet it is as it were an appendix to the preceding doctrine. For the vivifying light of the Gospel ought to scatter and dissipate, not only darkness, but also all mists, from the minds of the godly. The Apostle not only condemns idolatry, but commands us to beware of all images and idols; by which he intimates, that the worship of God cannot continue uncorrupted and pure whenever men begin to be in love with idols or images. For so innate in us is superstition, that the least occasion will infect us with its contagion. Dry wood will not so easily burn when coals are put under it, as idolatry will lay hold on and engross the minds of men, when an occasion is given to them. And who does not see that images are the sparks? What sparks do I say? nay, rather torches, which are sufficient to set the whole world on fire. The Apostle at the same time does not only speak of statues, but also of altars, and includes all the instruments of superstitions. Moreover, the Papists are ridiculous, who pervert this passage and apply it to the statues of Jupiter and Mercury and the like, as though the Apostle did not teach generally, that there is a corruption of religion whenever a corporeal form is ascribed to God, or whenever statues and pictures form a part of his worship. Let us then remember that we ought carefully to continue in the spiritual worship of God, so as to banish far from us everything that may turn us aside to gross and carnal superstitions. end of the first epistle of John

Little children - This is a favorite mode of address with John, (see the notes at 1-John 2:1), and it was proper to use it in giving his parting counsel; embracing, in fact, all that he had to say - that they should keep themselves from idols, and suffer nothing to alienate their affections from the true God. His great object had been to lead them to the knowledge and love of God, and all his counsels would be practically followed, if, amidst the temptations of idolatry, and the allurements of sin, nothing were allowed to estrange their hearts from him.
Keep yourselves from idols - From worshipping them; from all that would imply communion with them or their devotees. Compare the notes at 1-Corinthians 10:14. The word rendered "idols" here (εἰδώλων eidōlōn) means, properly, an image, specter, shade - as of the dead; then any image or figure which would represent anything, particularly anything invisible; and hence anything designed to represent God, and that was set up with a view to be acknowledged as representing him, or to bring, him, or his perfections, more vividly before the mind. The word is applicable to idol-gods - pagan deities, 1-Corinthians 8:4, 1-Corinthians 8:7; 1-Corinthians 10:19; Romans 2:22; 2-Corinthians 6:16; 1-Thessalonians 1:9; but it would, also, be applicable to any "image" designed to represent the true God, and through or by which the true God was to be adored. The essential things in the word seem to be:
(a) an image or representation of the Deity, and,
(b) the making of that an object of adoration instead of the true God.
Since one of these things would be likely to lead to the other, both are forbidden in the prohibitions of idolatry, Exodus 20:4-5. This would forbid all attempts to represent God by paintings or statuary; all idol-worship, or worship of pagan gods; all images and pictures that would be substituted in the place of God as objects of devotion, or that might transfer the homage from God to the image; and all giving of those affections to other beings or objects which are due to God. why the apostle closed this Epistle with this injunction he has not stated, and it may not be easy to determine. It may have been for such reasons as these:
(1) Those to whom he wrote were surrounded by idolaters, and there was danger that they might fall into the prevailing sin, or in some way so act as to be understood to lend their sanction to idolatry.
(2) in a world full of alluring objects, there was danger then, as there is at all times, that the affections should be fixed on other objects than the supreme God, and that what is due to him should be withheld.
It may be added, in the conclusion of the exposition of this Epistle, that the same caution is as needful for us as it was for those to whom John wrote. We are not in danger, indeed, of bowing down to idols, or of engaging in the grosser forms of idol-worship. But we may be in no less danger than they to whom John wrote were, of substituting other things in our affections in the place of the true God, and of devoting to them the time and the affection which are due to him. Our children it is possible to love with such an attachment as shall effectually exclude the true God from the heart. The world - "its wealth, and pleasures, and honors - we may love with a degree of attachment such as even an idolater would hardly shew to his idol-gods; and all the time which he would take in performing his devotions in an idol-temple, we may devote with equal fervor to the service of the world. There is practical idolatry all over the world; in nominally Christian lands as well as among the pagan; in families that acknowledge no God but wealth and fashion; in the hearts of multitudes of individuals who would scorn the thought of worshipping at a pagan altar; and it is even to be found in the heart of many a one who professes to be acquainted with the true God, and to be an heir of heaven. God should have the supreme place in our affections. The love of everything else should be held in strict subordination to the love of him.
He should reign in our hearts; be acknowledged in our closets, our families, and in the place of public worship; be submitted to at all times as having a right to command and control us; be obeyed in all the expressions of his will, by his word, by his providence, and by his Spirit; be so loved that we shall be willing to part without a complaint with the dearest object of affection when he takes it from us; and so that, with joy and triumph, we shall welcome his messenger, "the angel of death," when he shall come to summon us into his presence. To all who may read these illustrations of the Epistle of the "beloved disciple," may God grant this inestimable blessing and honor. Amen.

Little children - Τεκνια· Beloved children; he concludes with the same affectionate feeling with which he commenced.
Keep yourselves from idols - Avoid the idolatry of the heathens; not only have no false gods, but have the true God. Have no idols in your houses, none in your churches, none in your hearts. Have no object of idolatrous worship; no pictures, relics, consecrated tapers, wafers, crosses, etc., by attending to which your minds may be divided, and prevented from worshipping the infinite Spirit in spirit and in truth.
The apostle, says Dr. Macknight cautioned his disciples against going with the heathens into the temple of their idol gods, to eat of their feasts upon the sacrifices they had offered to these gods; and against being present at any act of worship which they paid them; because, by being present, they participated of that worship, as is plain from what St. Paul has written on the subject, 1-Corinthians 8:10 (note).
That is a man's idol or god from which he seeks his happiness; no matter whether it be Jupiter, Juno, Apollo, Minerva, Venus, or Diana; or pleasure, wealth, fame, a fine house, superb furniture, splendid equipage, medals, curiosities, books, titles, human friendships, or any earthly or heavenly thing, God, the supreme good, only excepted. That is a man's idol which prevents him from seeking and finding his All in God.
Wiclif ends his epistle thus: My little sones, kepe ye you fro mawmitis, i.e. puppets, dolls, and such like; for thus Wiclif esteemed all images employed in religious worship. They are the dolls of a spurious Christianity, and the drivellings of religion in nonage and dotage. Protestants, keep yourselves from such mawmets!
Amen - So be it! So let it be! And so it shall be, God being our helper, for ever and ever!

(19) Little children, keep yourselves from idols. Amen.
(19) He expresses a plain precept of taking heed of idols: which he contrasts with the only true God, that with this seal he might seal up all the former doctrine.

Little children, keep yourselves from idols, Amen. From Heathen idols and idolatry, into which the saints in those times might be liable to be drawn, by reason of their dwelling among Heathen idolaters, and being related to them, and by the too great freedom used in eating things sacrificed to idols in their temples; and from all other idols that might be introduced by some who went by the name of Christians, as the Gnostics, who worshipped the images of Simon and Helena; and the passage may be an antidote against the worshipping of images, afterwards introduced by the Papists. Moreover, errors and false doctrines, which are the figments of men's minds, and what they are fond of, may be called idols, and should be guarded against, and abstained from; as also the lusts of men's hearts, and all the evil things that are in the world, which are adored by the men of it; and even every creature that is loved too much is an idol; hence covetousness is called idolatry; nor should any creature or thing be loved more than God or Christ: the one only living and true God, Father, Son, and Spirit, he is only to be worshipped, feared, and loved.

Affectionate parting caution.
from idols--Christians were then everywhere surrounded by idolaters, with whom it was impossible to avoid intercourse. Hence the need of being on their guard against any even indirect compromise or act of communion with idolatry. Some at Pergamos, in the region whence John wrote, fell into the snare of eating things sacrificed to idols. The moment we cease to abide "in Him that is true (by abiding) in Jesus Christ," we become part of "the world that lieth in the wicked one," given up to spiritual, if not in all places literal, idolatry (Ephesians 5:5; Colossians 3:5).

Keep yourselves from idols - From all worship of false gods, from all worship of images or of any creature, and from every inward idol; from loving, desiring, fearing anything more than God. Seek all help and defence from evil, all happiness in the true God alone.
