Surely conversion is a matter between man and his Maker who alone knows his creatures' hearts. A conversion without a clean heart is, in my opinion, a denial of God and Religion. Conversion without cleanliness of heart can only be a matter of sorrow, not joy, to a godly person.
When we realize finally that we aren't God's given children, we'll understand satire. Humor is really laughing off a hurt, grinning at misery.
