'Excuse' in the Bible

Do you [who worship idols] not know? Have you not heard?Has it not been told to you from the beginning?Have you not understood from the foundations of the earth [the omnipotence of God and the stupidity of bowing to idols]?

If I had not come and spoken to them, they would not have [the guilt of their] sin; but now they have no excuse for their sin.

For ever since the creation of the world His invisible attributes, His eternal power and divine nature, have been clearly seen, being understood through His workmanship [all His creation, the wonderful things that He has made], so that they [who fail to believe and trust in Him] are without excuse and without defense.

Therefore you have no excuse or justification, everyone of you who [hypocritically] judges and condemns others; for in passing judgment on another person, you condemn yourself, because you who judge [from a position of arrogance or self-righteousness] are habitually practicing the very same things [which you denounce].

They show that the essential requirements of the Law are written in their hearts; and their conscience [their sense of right and wrong, their moral choices] bearing witness and their thoughts alternately accusing or perhaps defending them

For you, my brothers, were called to freedom; only do not let your freedom become an opportunity for the sinful nature (worldliness, selfishness), but through love serve and seek the best for one another.
