I find it pathetic that God would give us instincts such as the 7 deadly sins and then tell us to not do them. Who is he to challenge us. What does he stand to gain by making us prove ourselves.
It is natural for lust after other people. Why shouldn't we? God didn't tell us not to, the bible does. What do we stand to gain by restricting our natural instincts? A place in heaven? Pffft... what do we have to base this on? The bible, hardly convincing.
I could never be a Christian, i think it is abhorent to prevent myself from doing things that come naturally to me.
What is natural is the instinct to procreate, to preserve our gene pool, we share this with irrational brutes, but because of our rationality God gave us the Moral Law to live by we are rational thus we can work it out, we can tell what is natural for humans and what isnt natural for humans, brutes may commit unnatural acts but they dont have the power of reason to know any better, we are miles apart from other irrational brutes, why behave like they do? I don't think that you could become a Christian either, not to worry though heaven will be glorious even without you in it.
