Yes, as a lapsed one myself, I believe they preach it as they need it the most, as the self proclaimed representatives of the creator of the universe would, when happening to be historical blood thirsty, wealth hoarding, human trafficking paedophile harbourers they are at their political core. Regardless, forgiveness is a necessary and helpful human value which religion did not invent, much like all of the moral arguments in apology of religion. If it works for you, thats fine. My position is also based on having grown up in it.
