3:1 你看父赐给我们是何等的慈爱，使我们得称为神的儿女。我们也真是他的儿女。世人所以不认识我们，是因未曾认识他。
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.
3:2 亲爱的弟兄阿，我们现在是神的儿女，将来如何，还未显明。但我们知道主若显现，我们必要像他。因为必得见他的真体。
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.
3:3 凡向他有这指望的，就洁净自己，像他洁净一样。
And every man that hath this hope in him purifieth himself, even as he is pure.
3:4 凡犯罪的，就是违背律法。违背律法就是罪。
Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law.
3:5 你们知道主曾显现，是要除掉人的罪。在他并没有罪。
And ye know that he was manifested to take away our sins; and in him is no sin.
3:6 凡住在他里面的，就不犯罪。凡犯罪的，是未曾看见他，也未曾认识他。
Whosoever abideth in him sinneth not: whosoever sinneth hath not seen him, neither known him.
3:7 小子们哪，不要被人诱惑，行义的才是义人。正如主是义的一样。
Little children, let no man deceive you: he that doeth righteousness is righteous, even as he is righteous.
3:8 犯罪的是属魔鬼，因为魔鬼从起初就犯罪。神的儿子显现出来，为要除灭魔鬼的作为。
He that committeth sin is of the devil; for the devil sinneth from the beginning. For this purpose the Son of God was manifested, that he might destroy the works of the devil.
3:9 凡从神生的就不犯罪，因神的道（原文作种）存在他心里。他也不能犯罪，因为他是由神生的。
Whosoever is born of God doth not commit sin; for his seed remaineth in him: and he cannot sin, because he is born of God.
3:10 从此就显明出谁是神的儿女，谁是魔鬼的儿女。凡不行义的，就不属神。不爱弟兄的也是如此。
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.
3:11 我们应当彼此相爱。这就是你们从起初所听见的命令。
For this is the message that ye heard from the beginning, that we should love one another.
3:12 不可像该隐。他是属那恶者，杀了他的兄弟。为什么杀了他呢。因为自己的行为是恶的，兄弟的行为是善的。
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.
3:13 弟兄们，世人若恨你们，不要以为希奇。
Marvel not, my brethren, if the world hate you.
3:14 我们因为爱弟兄，就晓得是已经出死入生了。没有爱心的，仍住在死中。
We know that we have passed from death unto life, because we love the brethren. He that loveth not his brother abideth in death.
3:15 凡恨他弟兄的，就是杀人的。你们晓得凡杀人的，没有永生存在他里面。
Whosoever hateth his brother is a murderer: and ye know that no murderer hath eternal life abiding in him.
3:16 主为我们舍命，我们从此就知道何为爱。我们也应当为弟兄舍命。
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.
3:17 凡有世上财物的，看见弟兄穷乏，却塞住怜恤的心，爱神的心怎能存在他里面呢。
But whoso hath this world's good, and seeth his brother have need, and shutteth up his bowels of compassion from him, how dwelleth the love of God in him?
3:18 小子们哪，我们相爱，不要只在言语和舌头上。总要在行为和诚实上。
My little children, let us not love in word, neither in tongue; but in deed and in truth.
3:19 从此就知道我们是属真理的，并且我们的心在神面前可以安稳。
And hereby we know that we are of the truth, and shall assure our hearts before him.
3:20 我们的心若责备我们，神比我们的心大，一切事没有不知道的。
For if our heart condemn us, God is greater than our heart, and knoweth all things.
3:21 亲爱的弟兄阿，我们的心若不责备我们，就可以向神坦然无惧了。
Beloved, if our heart condemn us not, then have we confidence toward God.
3:22 并且我们一切所求的，就从他得着。因为我们遵守他的命令，行他所喜悦的事。
And whatsoever we ask, we receive of him, because we keep his commandments, and do those things that are pleasing in his sight.
3:23 神的命令就是叫我们信他儿子耶稣基督的名，且照他所赐给我们的命令彼此相爱。
And this is his commandment, That we should believe on the name of his Son Jesus Christ, and love one another, as he gave us commandment.
3:24 遵守神命令的，就住在神里面。神也住在他里面。我们所以知道神住在我们里面，是因他所赐给我们的圣灵。
And he that keepeth his commandments dwelleth in him, and he in him. And hereby we know that he abideth in us, by the Spirit which he hath given us.
