Christians can't do that, median. Only God can because he is the Creator and Supreme King.
No, your god is a bully. "Might makes right" is not a morality worth following.
Since God is infinite, any sin against Him deserves infinite punishment.
You have this completely and utterly ass-backwards, Skeptic. The vast scope of an "infinite" being -- omnipotent and/or omnipresent and/or eternal -- suggests that it cannot be harmed by mortals unless it wants
to be harmed (in which case, the "sinner" is actually doing its will and is off the hook). Thus, all "sins" are not infinite, but infinitesimal.
Since humans are not infinite, sins against us don't merit infinite punishment.
I have news for you, young man: There is nothing
that merits infinite punishment. Ever. There are no exceptions to this rule, be one a god or be one a mortal.
To drive this point home once and for all, perhaps you should meditate on this:Imagine that someone whom you love dearly has offended your god in some way. Your beloved has been sentenced to eternal punishment. In your imagination, spend one hour a day watching the torture of this person, without flinching or turning away. Look at the wounds. Listen to his or her scream for mercy, and listen for the utter silence and indifference of your god.
Do this for one hour every night at the same time, for 100 nights.
