Is not Wrath and hatred the second deadliest sin? Is it not taught that we should love our brothers and sisters?
The Bible has been changed and warped through time. Few people appreciate that the Bible is not in its original format, or what certain ideas actually mean. Many people say "thou shalt not steal," but few recognize that the Commandment in Hebrew refers to man, ie. slavery.
Judgement is for God, not man. We should love God, and we should love our fellow man. If we cannot show love on Earth, how can we show love in Heaven?
