1 Jo 3:5 And ye know that he was manifested to take away our sins; and in him is no sin.
Here's the context: 1 John 3:4 Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law. 5 And ye know that he was manifested to take away our sins (our transgressions); and in him is no sin (transgression).
What's the subject, indwelling sin? No! Transgression of the law. So Christ never transgressed the law. That's all it is stating. Otherwise you're adding to the Scriptures.
