And most people, whether Christian or not, reject that Christ. It's a good thing that UR is true!
Another verse taken out of context to support something that it doesn't really support.
Beloved, believe not every spirit, but prove the spirits, whether they are of God; because many false prophets are gone out into the world.Hereby know ye the Spirit of God: every spirit that confesseth that Jesus Christ is come in the flesh is of God:and every spirit that confesseth not Jesus is not of God: and this is the spirit of the antichrist, whereof ye have heard that it cometh; and now it is in the world already.Ye are of God, my 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 as of the world, and the world heareth them.We are of God: he that knoweth God heareth us; he who is not of God heareth us not. By this we know the spirit of truth, and the spirit of error.Beloved, let us love one another: for love is of God; and every one that loveth is begotten of God, and knoweth God.He that loveth not knoweth not God; for God is love.Herein was the love of God manifested in us, that God hath sent his only begotten Son into the world that we might live through him.Herein is love, not that we loved God, but that he loved us, and sent his Son to be the propitiation for our sins.Beloved, if God so loved us, we also ought to love one another.No man hath beheld God at any time: if we love one another, God abideth in us, and his love is perfected in us:hereby we know that we abide in him and he in us, because he hath given us of his Spirit.And we have beheld and bear witness that the Father hath sent the Son to be the Saviour of the world.Whosoever shall confess that Jesus is the Son of God, God abideth in him, and he in God. - 1 John 4:1-15
Bible Gateway passage: 1 John 4:1-15 - American Standard Version
It's the spirit of the anti-christ that leads to saying Jesus is not the Christ. Notice the verse right after the one you quoted. Whomever confesses that Jesus is the Son of God. All these verses speak of a worldly spirit and a Godly spirit. The worldly spirit is against Christ and will not confess him as the Christ the Son of God.
Look at what John says in the previous chapter.
Behold what manner of love the Father hath bestowed upon us, that we should be called children of God; and such we are. For this cause the world knoweth us not, because it knew him not.Beloved, now are we children of God, and it is not yet made manifest what we shall be. We know that, if he shall be manifested, we shall be like him; for we shall see him even as he is.And every one that hath this hope set on him purifieth himself, even as he is pure.Every one that doeth sin doeth also lawlessness; and sin is lawlessness.And ye know that he was manifested to take away sins; and in him is no sin.Whosoever abideth in him sinneth not: whosoever sinneth hath not seen him, neither knoweth him.My little children, let no man lead you astray: he that doeth righteousness is righteous, even as he is righteous:he that doeth sin is of the devil; for the devil sinneth from the beginning. To this end was the Son of God manifested, that he might destroy the works of the devil.Whosoever is begotten of God doeth no sin, because his seed abideth in him: and he cannot sin, because he is begotten of God.In this the children of God are manifest, and the children of the devil: whosoever doeth not righteousness is not of God, neither he that loveth not his brother. - 1 John 3:1-10
Bible Gateway passage: 1 John 3:1-10 - American Standard Version
Believers do not practice sin. The world does practice sin. There are children of God and children of the devil.
Jesus came to destroy the works of the devil. But it is the CHILDREN OF GOD. The world does not know is because it does not know God. What happens to those that do not know God and are of the devil?
My little children, these things write I unto you that ye may not sin. And if any man sin, we have an Advocate with the Father, Jesus Christ the righteous:and he is the propitiation for our sins; and not for ours only, but also for the whole world.And hereby we know that we know him, if we keep his commandments.He that saith, I know him, and keepeth not his commandments, is a liar, and the truth is not in him;but whoso keepeth his word, in him verily hath the love of God been perfected. Hereby we know that we are in him:he that saith he abideth in him ought himself also to walk even as he walked.Beloved, no new commandment write I unto you, but an old commandment which ye had from the beginning: the old commandment is the word which ye heard.Again, a new commandment write I unto you, which thing is true in him and in you; because the darkness is passing away, and the true light already shineth.He that saith he is in the light and hateth his brother, is in the darkness even until now.He that loveth his brother abideth in the light, and there is no occasion of stumbling in him.Who is the liar but he that denieth that Jesus is the Christ? This is the antichrist, even he that denieth the Father and the Son.Whosoever denieth the Son, the same hath not the Father: he that confesseth the Son hath the Father also. - 1 John 2:1-10,22-23
Bible Gateway passage: 1 John 2:1-10, 1 John 2:22-23 - American Standard Version
These verses help clarify each other. Jesus provided a way for all sinners to be with God and Christ. But those that deny Christ are not with him or the father. And they are LIARS. What happens to them?
But for the fearful, and unbelieving, and abominable, and murderers, and fornicators, and sorcerers, and idolaters, and all liars, their part shall be in the lake that burneth with fire and brimstone; which is the second death.and there shall in no wise enter into it anything unclean, or he that maketh an abomination and a lie: but only they that are written in the Lamb’s book of life. - Revelation 21:8,27
