Romans 1:18-21 For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who hold the truth in unrighteousness; beause that which may be known of God is manifest in them; for God hath shewed it unto them. For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without exuse:
Put plainly we already know the truth, God has already put it inside each of us. There is no need to preach about hell, as some do, drawing people by fear. In contrast
Romans 2:3-4 And thinkest thou this, O man that judgest them which do such things, and doest the same, that thou shalt escape the judgement of God? Or despisest thou the riches of his goodness and forbearance and longsuffering; not knowing that the goodness of God leadeth them to repentence.
Fear of damnation doesn't lead people to repentence. God's Love and goodness does. Yes, there is a time and place to rebuke and exhortation, but when trying to save a "sinner" that isn't the time. Many will argue that many accept Jesus after putting the"fear" of God in them, that is temporary, which is why we have so many "backsliders" or revolving door christians. Once the true Love of God is felt, that is when a lifetime Believer is Born.
