7 Bible Verses about Knowledge, Of Sin

When Gentiles, who have not the law, do by nature things required by the law, they are a law to themselves, even though they do not have the law. They show that the requirements of the law are written on their hearts, their conscience also bearing witness, and their thoughts accusing or else excusing them

let us draw near with a true heart in full assurance of faith, having our hearts sprinkled clean from an evil conscience and our bodies washed with pure water.

Therefore no flesh will be justified in his sight by works of the law, for through the law comes knowledge of sin.

(For sin was in the world before the law was given, but sin is not counted when there is no law.

What shall we say, then? Is the law sin? Certainly not! Indeed, I would not have known what sin was except through the law. For I would not have known what coveting really was if the law had not said, "You shall not covet."

Nevertheless I tell you the truth: it is to your advantage that I go away. For if I do not go away, the Counselor will not come to you; but if I go, I will send him to you. And when he comes, he will convict the world of sin, and of righteousness, and of judgment: of sin, because they do not believe in me;read more.
of righteousness, because I go to the Father, and you see me no more; of judgment, because the ruler of this world is judged.

for our gospel came to you not only in word, but also in power and in the Holy Spirit and with full conviction. You know what kind of men we proved to be among you for your sake.
