Ezekiel 18:24 “But when a righteous man turns away from his righteousness and commits iniquity, and does according to all the abominations that the wicked man does, shall he live? All the righteousness which he has done shall not be remembered; because of the unfaithfulness of which he is guilty and the sin which he has committed, because of them he shall die.
Revelation 20:15 And anyone not found written in the Book of Life was cast into the lake of fire.
Deuteronomy 29:18-19 so that there may not be among you man or woman or family or tribe, whose heart turns away today from the LORD our God, to go and serve the gods of these nations, and that there may not be among you a root bearing bitterness or wormwood; and so it may not happen, when he hears the words of this curse, that he blesses himself in his heart, saying, ‘I shall have peace, even though I follow the dictates of my heart’—as though the drunkard could be included with the sober.
2 Chronicles 24:19-21 Yet He sent prophets to them, to bring them back to the LORD; and they testified against them, but they would not listen. Then the Spirit of God came upon Zechariah the son of Jehoiada the priest, who stood above the people, and said to them, "Thus says God: "Why do you transgress the commandments of the LORD, so that you cannot prosper? Because you have forsaken the LORD, He also has forsaken you."" So they conspired against him, and at the command of the king they stoned him with stones in the court of the house of the LORD.
Job 27:1-6 Moreover Job continued his discourse, and said: “As God lives, who has taken away my justice, And the Almighty, who has made my soul bitter, As long as my breath is in me, And the breath of God in my nostrils, My lips will not speak wickedness, Nor my tongue utter deceit. Far be it from me That I should say you are right; Till I die I will not put away my integrity from me. My righteousness I hold fast, and will not let it go; My heart shall not reproach me as long as I live.
Hebrews 10:26-29 For if we sin willfully after we have received the knowledge of the truth, there no longer remains a sacrifice for sins, but a certain fearful expectation of judgment, and fiery indignation which will devour the adversaries. Anyone who has rejected Moses' law dies without mercy on the testimony of two or three witnesses. Of how much worse punishment, do you suppose, will he be thought worthy who has trampled the Son of God underfoot, counted the blood of the covenant by which he was sanctified a common thing, and insulted the Spirit of grace?
