but if we [really] walk in the Light [that is, live each and every day in conformity with the precepts of God], as He Himself is in the Light, we have [true, unbroken] fellowship with one another [He with us, and we with Him], and the blood of Jesus His Son cleanses us from all sin [by erasing the stain of sin, keeping us cleansed from sin in all its forms and manifestations].

If we say that we have no sin, we are false to ourselves and there is nothing true in us.

If we say openly that we have done wrong, he is upright and true to his word, giving us forgiveness of sins and making us clean from all evil.

The man who says, I have knowledge of him, and does not keep his laws, is false, and there is nothing true in him:

but he that observes his precepts, loves God with a true and perfect love: 'tis by this we know that we are truly christians.

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.

From us, it is true, they went out, but they had never belonged to us; for, if they had belonged to us, they would have remained among us. They left us that it might be made clear that they do not, any of them, belong to us.

I have not sent you this letter because you have no knowledge of what is true, but because you have knowledge, and because that which is false has nothing in common with that which is true.

I am writing these things to you about those whose purpose is that you may be turned out of the true way.

And as for you, the anointing which ye received of him abideth in you, and ye need not that any one teach you; but as his anointing teacheth you; concerning all things, and is true, and is no lie, and even as it taught you, ye abide in him.

My little children, let no man take you out of the true way: he who does righteousness is upright, even as he is upright;

My children, do not let our love be mere words, or end in talk; let it be true and show itself in acts.

In this way we may be certain that we are true, and may give our heart comfort before him,

We are of God: he who has the knowledge of God gives ear to us; he who is not of God does not give ear to us. By this we may see which is the true spirit, and which is the spirit of error.

In this way is seen the true love, not that we loved God but that He loved us and sent His Son to be the atoning sacrifice for our sins.

There is no fear in love: true love has no room for fear, because where fear is, there is pain; and he who is not free from fear is not complete in love.

For the [true] love of God is this: that we habitually keep His commandments and remain focused on His precepts. And His commandments and His precepts are not difficult [to obey].

for he that is a true christian, overcomes the world: by obtaining faith, we have gain'd a victory over the world.

And the Spirit is the witness, because the Spirit is true.

If we take the witness of men to be true, the witness of God is greater: because this is the witness which God has given about his Son.

we know that a true christian will not commit such a sin, for he that is the child of God keeps upon his guard, so that the wicked spirit does not approach him.

And we know that the Son of God is come, and hath given us an understanding, that we 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.
