I believe they call that trump verse hermeneutics. Fancy words for taking a concordance and finding a proof-text to say the opposite of what you don't want to see but is staring you squarely in the face. Also known as avoiding conviction or justifying your sin...
OK, I'm being cynical in that last statement, but you understand what I mean. The entire book of 1 John is saying you don't have to sin. In fact, if you are born of God, you can't sin. But that's too scary to face. It means I have to give up my favorite hobby—playing god! We can't let that happen, so we take one verse out of context and use that to countermand the clear trajectory of the rest of the book.
Lord deliver us from ourselves!
