'Sin' in the Bible

John came, and gave baptism in the waste land, preaching baptism as a sign of forgiveness of sin for those whose hearts were changed.

And saying, The time has come, and the kingdom of God is near: let your hearts be turned from sin and have faith in the good news.

And it happened that Jesus was reclining at the table in Levi’s house, and many tax collectors and sinners [including non-observant Jews] were eating with Him and His disciples; for there were many of them and they were following Him.

When Jesus heard this, He said to them, “Those who are healthy have no need of a physician, but [only] those who are sick; I did not come to call the righteous, but sinners [who recognize their sin and humbly seek forgiveness].”

But whoever blasphemes against the Holy Spirit never has forgiveness, but is guilty of an eternal sin”—

acts of greed and covetousness, wickedness, deceit, unrestrained conduct, envy and jealousy, slander and profanity, arrogance and self-righteousness and foolishness (poor judgment).

"If anyone causes one of these little ones who believe in me to sin, it would be better for him if a large millstone were hung around his neck and he were thrown into the sea.

So if your hand causes you to sin, cut it off. It's better for you to enter life injured than to have two hands and go to hell, to the fire that cannot be put out.

[where their worm does not die, and the fire is not put out.]

And if your foot causes you to sin, cut it off. It's better for you to enter life crippled than to have two feet and be thrown into hell.

And if your eye causes you to sin, tear it out. It's better for you to enter the kingdom of God with one eye than to have two eyes and be thrown into hell.
