Cannot they then be saved, who, continuing in their wicked and ungrateful lives, are not converted to God?

By no means; for the holy scripture declares that no unchaste person, idolater, adulterer, thief, covetous man, drunkard, slanderer, robber, or any such like, shall inherit the kingdom of God. (a)

(a) 1 Cor.6:9 Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind, 1 Cor.6:10 Nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God. Eph.5:5 For this ye know, that no whoremonger, nor unclean person, nor covetous man, who is an idolater, hath any inheritance in the kingdom of Christ and of God. Eph.5:6 Let no man deceive you with vain words: for because of these things cometh the wrath of God upon the children of disobedience. 1 John 3:14 We know that we have passed from death unto life, because we love the brethren. He that loveth not his brother abideth in death.
