Numre 12:14

Verse 14. But perception is given from Divine Good, that even when interior good is but vitiated slightly by falsity from selfish love, the consciousness of sin and of the necessity of purification by regeneration are present; how much more then is this the case when there is the profanation of good and truth! It must needs be therefore, that while any vestige of profanation remains with man, he is excluded from heaven, and that only when he is fully regenerated can he enter therein.
