18 We are certain that one who is a child of God will do no sin, but the Son of God keeps him so that he is not touched by the Evil One. 19 We are certain that we are of God, but all the world is in the power of the Evil One. 20 And we are certain that the Son of God has come, and has given us a clear vision, so that we may see him who is true, and we are in him who is true, in his Son Jesus Christ. He is the true God and eternal life.
Matthew Henry's Commentary on 1 John 5:18-20
Commentary on 1 John 5:18-21
(Read 1 John 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.
