1 John 4:1-21
1 Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world.
2 Hereby know ye the Spirit of God: Every spirit that confesseth that Jesus Christ is come in the flesh is of God:
3 And every spirit that confesseth not that Jesus Christ is come in the flesh is not of God: and this is that spirit of antichrist, whereof ye have heard that it should come; and even now already is it in the world.
4 Ye are of God, little children, and have overcome them: because greater is he that is in you, than he that is in the world.
5 They are of the world: therefore speak they of the world, and the world heareth them.
6 We are of God: he that knoweth God heareth us; he that is not of God heareth not us. Hereby know we the spirit of truth, and the spirit of error.
7 Beloved, let us love one another: for love is of God; and every one that loveth is borna of God, and knoweth God.
8 He that loveth not knoweth not God; for God is love.
9 In this was manifested the love of God toward us, because that God sent his only begotten Son into the world, that we might live through him.
10 Herein is love, not that we loved God, but that he loved us, and sent his Son to be the propitiation for our sins.
11 Beloved, if God so loved us, we ought also to love one another.
12 No man hath seen God at any time. If we love one another, God dwelleth in us, and his love is perfected in us.
13 Hereby know we that we dwell in him, and he in us, because he hath given us of his Spirit.
14 And we have seen and do testify that the Father sent the Son to be the Saviour of the world.
15 Whosoever shall confess that Jesus is the Son of God, God dwelleth in him, and he in God.
16 And we have known and believed the love that God hath to us. God is love; and he that dwelleth in love dwelleth in God, and God in him.
17 Herein is our loveb made perfect, that we may have boldness in the day of judgment: because as he is, so are we in this world.
18 There is no fear in love; but perfect love casteth out fear: because fear hath torment. He that feareth is not made perfect in love.
19 We love him, because he first loved us.
20 If a man say, I love God, and hateth his brother, he is a liar: for he that loveth not his brother whom he hath seen, how can he love God whom he hath not seen?
21 And this commandment have we from him, That he who loveth God love his brother also.
Two closely related perils threaten our fellowship with God as love, false prophets and the spirit which actuates them. Teaching is to be tested by the indwelling Spirit. All who refuse to confess that Jesus is Lord do so because they are of the world. At the root of every heresy concerning Jesus there has been worldliness in some form. To degrade the Person of Christ is to shake the foundations of faith. There can be no character which is according to God when the creed concerning Christ is a denial of the Spirit's test.
The apostle then makes an appeal by the employment of two arguments. First, that the nature of God is love, and therefore those who are His children should love. The second, that God has manifested His love.
The argument and appeal now issue in the declaration that no man has seen God, but the essence of the unseen God has been revealed in Christ, and now is to be revealed through His children. There is only one manifestation of God which is prevailing and powerful, and that is love. This is seen in the Son. All the glories and perfections of the Son are ours in Him. That is the apostle's consciousness of the glorious perfection of the provision which lends sternness to the words, "If a man say, I love God, and hateth his brother, he is a liar." To every person in actual union with God in Christ, love is possible. This, moreover, is not a privilege merely; it is a stem duty. The world still waits for the knowledge of God, which can come only through His revelation in the love of His children.
