"who hold the truth in unrighteousness" from KJV, to me, has totoally different context than "who suppress the truth by their wickedness" from NIV and many other translations.
Those who are against the truth, BY vs. IN unrighteousness, to me is the difference between those un-born Christians who does feel pain with their sins vs. all sinners in general.
If I understand the verse as the former case (Romans 1:18 refers to un-born again Christians still in sins, or no effort to move away from them), the the following verses all makes much more sense to me.
Wondering if this is because I am not an English native speaker who understands the "in" and "by", or there could be a profound differentiation. Can anyone share your thoughts on this?
Just listed some verses that make much more sense with the former perspective:
1:19 Because that which may be known of God is manifest in them; for God hath shewed it unto them.
1:21 Because that, when they knew God, they glorified him not as God, neither were thankful;
1:25 Who changed the truth of God into a lie, and worshipped and served the creature more than the Creator
2:4 Or despisest thou the riches of his goodness and forbearance and longsuffering; not knowing that the goodness of God leadeth thee to repentance?
2:13 For not the hearers of the law are just before God, but the doers of the law shall be justified.
2:21-23 Thou therefore which teachest another, teachest thou not thyself? thou that preachest a man should not steal, dost thou steal?
Thou that sayest a man should not commit adultery, dost thou commit adultery? thou that abhorrest idols, dost thou commit sacrilege?
Thou that makest thy boast of the law, through breaking the law dishonourest thou God?
3:5 But if our unrighteousness commend the righteousness of God, what shall we say? Is God unrighteous who taketh vengeance? (I speak as a man)
3:9 What then? are we better than they? No, in no wise: for we have before proved both Jews and Gentiles, that they are all under sin;
To me, all these verses (just some) above ask for our repentance, who are within churches but do not follow Jesus with full heart.
