"I have not come to call the righteous but sinners to repentance." (Luke 5:32).
The most 'sinful' people in deepest need of religion are the spoiled brats who currently take the profound and inextricable influence of religion all around them for granted. Traditionally, it is the poor and uneducated in most need of GOD's wisdom and knowledge, who came to be this way through the generational consequences of sin. However, they are now second in wretchedness to the above who are in greater danger of not returning to GOD because of spiritual 'lukewarmness' and the superficial appearance of wealth and safety.
15‘I know your deeds, that you are neither cold nor hot; I wish that you were cold or hot. 16‘So because you are lukewarm, and neither hot nor cold, I will spit you out of My mouth. 17‘Because you say, “I am rich, and have become wealthy, and have need of nothing,” and you do not know that you are wretched and miserable and poor and blind and naked, 18I advise you to buy from Me gold refined by fire so that you may become rich, and white garments so that you may clothe yourself, and that the shame of your nakedness will not be revealed; and eye salve to anoint your eyes so that you may see. 19‘Those whom I love, I reprove and discipline; therefore be zealous and repent." (Revelation 3:15-19).
