The ransom sacrifice works very well.
A man is born and feels no guilt, no shame. As the years pass, his Christian family teach him to be ashamed because he is sinful and imperfect. The only way he can escape this sad condition is to accept the idea of a ransom sacrifice made on his behalf. He will then be shown mercy and be free of sin.
Alas he is then indebted to the Christian church that helped him strike this priceless bargain and of course to the invisible Christ for whom they claim to act.
Still better than staying a child of the Devil and living in sin with nothing to look forward to except death and maybe an eternity in Hell depending on how trendy your branch of Christianity is.
