5:18-21 All mankind are divided into two parties or dominions; that which belongs to God, and that which belongs to the wicked one. True believers belong to God: they are of God, and from him, and to him, and for him; while the rest, by far the greater number, are in the power of the wicked one; they do his works, and support his cause. This general declaration includes all unbelievers, whatever their profession, station, or situation, or by whatever name they may be called. The Son leads believers to the Father, and they are in the love and favour of both; in union with both, by the indwelling and working of the Holy Spirit. Happy are those to whom it is given to know that the Son of God is come, and to have a heart to trust in and rely on him that is true! May this be our privilege; we shall thus be kept from all idols and false doctrines, and from the idolatrous love of worldly objects, and be kept by the power of God, through faith, unto eternal salvation. To this living and true God, be glory and dominion for ever and ever. Amen.
18. (1Jo 3:9.)
We know—Thrice repeated emphatically, to enforce the three truths which the words preface, as matters of the brethren's joint experimental knowledge. This 1Jo 5:18 warns against abusing 1Jo 5:16, 17, as warranting carnal security.
whosoever—Greek, "every one who." Not only advanced believers, but every one who is born again, "sinneth not."
he that is begotten—Greek aorist, "has been (once for all in past time) begotten of God"; in the beginning of the verse it is perfect. "Is begotten," or "born," as a continuing state.
keepeth himself—The Vulgate translates, "The having been begotten of God keepeth HIM" (so one of the oldest manuscripts reads): so Alford. Literally, "He having been begotten of God (nominative pendent), it (the divine generation implied in the nominative) keepeth him." So 1Jo 3:9, "His seed remaineth in him." Still, in English Version reading, God's working by His Spirit inwardly, and man's working under the power of that Spirit as a responsible agent, is what often occurs elsewhere. That God must keep us, if we are to keep ourselves from evil, is certain. Compare Joh 17:15 especially with this verse.
that wicked one toucheth him not—so as to hurt him. In so far as he realizes his regeneration-life, the prince of this world hath nothing in him to fasten his deadly temptations on, as in Christ's own case. His divine regeneration has severed once for all his connection with the prince of this world.
