15 To the pure, all things are pure, but to the defiled and unbelieving, nothing is pure; but both their minds and their consciences are defiled. 16 They profess to know God, but they deny him by their works. They are detestable, disobedient, unfit for any good work.

28 And since they did not see fit to acknowledge God, God gave them up to a debased mind to do what ought not to be done. 29 They were filled with all manner of unrighteousness, evil, covetousness, malice. They are full of envy, murder, strife, deceit, maliciousness. They are gossips, 30 slanderers, haters of God, insolent, haughty, boastful, inventors of evil, disobedient to parents, 31 foolish, faithless, heartless, ruthless.

    the instruction of idols is but wood!

    the heart of the wicked is of little worth.

17 Now this I say and testify in the Lord, that you must no longer walk as the Gentiles do, in the futility of their minds. 18 They are darkened in their understanding, alienated from the life of God because of the ignorance that is in them, due to their hardness of heart.

5 The LORD saw that the wickedness of man was great in the earth, and that every intention of the thoughts of his heart was only evil continually.
