If we say that we have no sin, we deceive ourselves, and the truth is not in us.
God’s truth, as Scripture reveals it, does not have a full hold on us, is not controlling our thinking, if we make this claim. "In us" suggests not that we have the facts in our mental grasp but that they have control over us. They are in us as a thread is in a piece of cloth rather than as a coin is in a pocket. The same contrast exists between intellectual assent and saving faith.
