In what religion on earth does God justify irreverent people? In what religion does He actually save sinners? Answer: no religion. Every single religion on earth requires human worthiness as a prerequisite for salvation.
The Christian religion, especially, insists that irreverent people stop being irreverent long enough to ask God to save them. This religion is in fact the most hypocritical of all in that it demands that "helpless sinners" help themselves.
Let's contrast this with the truth, shall we?
