John 1:9

I am come a light into the world, that whosoever believeth on me should not abide in darkness.

Again, a new commandment I write unto you, which thing is true in him and in you: because the darkness is past, and the true light now shineth.

In him was life; and the life was the light of men.

And he said, It is a light thing that thou shouldest be my servant to raise up the tribes of Jacob, and to restore the preserved of Israel: I will also give thee for a light to the Gentiles, that thou mayest be my salvation unto the end of the earth.

The same came for a witness, to bear witness of the Light, that all men through him might believe.

But ye, brethren, are not in darkness, that that day should overtake you as a thief. Ye are all the children of light, and the children of the day: we are not of the night, nor of darkness. Therefore let us not sleep, as do others; but let us watch and be sober. For they that sleep sleep in the night; and they that be drunken are drunken in the night.

And we know that the Son of God is come, and hath given us an understanding, that we may know him that is true, and we are in him that is true, even in his Son Jesus Christ. This is the true God, and eternal life.

Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.

Then Jesus said unto them, Verily, verily, I say unto you, Moses gave you not that bread from heaven; but my Father giveth you the true bread from heaven.

If we say that we have no sin, we deceive ourselves, and the truth is not in us.

To the law and to the testimony: if they speak not according to this word, it is because there is no light in them.

I am the true vine, and my Father is the husbandman.

And there was much murmuring among the people concerning him: for some said, He is a good man: others said, Nay; but he deceiveth the people.

But if thine eye be evil, thy whole body shall be full of darkness. If therefore the light that is in thee be darkness, how great is that darkness!
