1 John - 3 John: Darkness is Passing

This is the message we have heard from him and declare to you: God is light; in him there is no darkness at all. If we claim to have fellowship with him yet walk in the darkness, we lie and do not live by the truth. But if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus, his Son, purifies us from all sin. - 1 John 1:5-7  NIV

This is the message, John says.  He can say it because he has seen Jesus.  He has walked and talked with him.  He saw him after he rose from the dead, he saw him ascend into heaven. 

   Behold, what manner of love the Father hath bestowed upon us, that we should be called the sons of God: therefore the world knoweth us not, because it knew him not.
   Beloved, now are we the sons of God, and it doth 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. - 1 John 3:1-2 KJV

Don't love the world, John says.  Do not love the world or anything in the world. If anyone loves the world, the love of the Father is not in him. For everything in the world—the cravings of sinful man, the lust of his eyes and the boasting of what he has and does—comes not from the Father but from the world. The world and its desires pass away, but the man who does the will of God lives forever.  - 1 John 2:15-17 NIV

It's all passing away, he says.  Even now many antichrists have come.  It's not hard to recognize the antichrists.  Who is the liar? It is whoever denies that Jesus is the Christ. Such a person is the antichrist—denying the Father and the Son. (1 John 2:21-23 NIV) but every spirit that does not acknowledge Jesus is not from God. This is the spirit of the antichrist, which you have heard is coming and even now is already in the world. (1 John 4:2-3 NIV)

  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.
  They are of the world: therefore speak they of the world, and the world heareth them. - 1 John 4:4-5 KJV

But you, who are of God have nothing to fear.  The world may appear dark, but it is passing away. The sons of God hear a different voice.  They no longer walk in darkness, but walk in the light.
