Strong's King James

If we say that we have not deviated, we make Him a liar, and His Word (Logos) is not in us."

The F.O.G*

[10] If we claim we've never sinned, we're not just mistaken - we're actually calling God a liar, showing His truth hasn't taken root in our lives. Such a claim reveals we haven't grasped the reality of our condition or the magnitude of His grace.If we claim we are without sin, we make Him out to be a liar, and the truth of His Divine Expression is not in us.

The F.O.G Paraphrase

if we may say—‘we have not sinned,’ a liar we make Him, and His word is not in us.
