Because with lies you have made the heart of the righteous sad, whom I have not made sad; and strengthened the hands of the wicked, that he should not return from his wicked way, by promising him life:
Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world. Hereby know you the Spirit of God: Every spirit that confesses that Jesus Christ is come in the flesh is of God: And every spirit that confesses not that Jesus Christ is come in the flesh is not of God: and this is that spirit of antichrist, where of you have heard that it should come; and even now already is it in the world. You are of God, little children, and have overcome them: because greater is he that is in you, than he that is in the world. They are of the world: therefore speak they of the world, and the world hear them. We are of God: he that know God hear us; he that is not of God hear not us. Hereby know we the spirit of truth, and the spirit of error.
He that commits sin is of the devil; for the devil sins from the beginning. For this purpose the Son of God was manifested, that he might destroy the works of the devil. Whosoever is born of God does not commit sin; for his seed remains in him: and he cannot sin, because he is born of God. In this the children of God are manifest, and the children of the devil: whosoever does not righteousness is not of God, neither he that loves not his brother. For this is the message that you heard from the beginning, that we should love one another. Not as Cain, who was of that wicked one, and slew his brother. And wherefore slew he him? Because his own works were evil, and his brother's righteous. Marvel not, my brethren, if the world hate you. We know that we have passed from death unto life, because we love the brethren. He that loves not his brother abides in death. Whosoever hates his brother is a murderer: and you know that no murderer have eternal life abiding in him. Hereby perceive we the love of God, because he laid down his life for us: and we ought to lay down our lives for the brethren.
Behold, what manner of love the Father has bestowed upon us, that we should be called the sons of God: therefore the world knows us not, because it knew him not. Beloved, now are we the sons of God, and it do not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is.
