Jesus never said that his followers would *go* to “Heaven” per se. He repeatedly indicated that the “Kingdom of Heaven” would *come* to them. To me, that seems like a pretty big difference. As far as I can ascertain from my reading, Heaven itself is a realm reserved strictly for God and His angels. Jesus said that no one has ever ascended there. (John 3:13) I suppose he would later become the first, if not the only, exception. (Elijah is disputable. 2 Kings:2)
On the whole men are more good than bad; that, however, isn't the real point. But they are more or less ignorant, and it is this that we call vice or virtue; the most incorrigible vice being that of an ignorance which fancies it knows everything and therefore claims for itself the right to kill. The soul of the murderer is blind; and there can be no true goodness nor true love without the utmost clear-sightedness.
