亲爱的弟兄阿，你们既然豫先知道这事，就当防备，恐怕被恶人的错谬诱惑，就从自己坚固的地步上坠落。
Ye therefore, beloved, seeing ye know these things before, beware lest ye also, being led away with the error of the wicked, fall from your own stedfastness.
你们却要在我们主救主耶稣基督的恩典和知识上有长进。愿荣耀归给他，从今直到永远。阿们。
But grow in grace, and in the knowledge of our Lord and Saviour Jesus Christ. To him be glory both now and for ever. Amen.
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.
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.
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.
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.
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.
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.
弟兄们，世人若恨你们，不要以为希奇。
Marvel not, my brethren, if the world hate you.
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.
