1 John 2:2-4

Young's Literal Translation

² and he -- he is a propitiation for our sins, and not for ours only, but also for the whole world,

³ and in this we know that we have known him, if his commands we may keep;

⁴ he who is saying, `I have known him,' and his command is not keeping, a liar he is, and in him the truth is not;
