"I tell you that he will avenge them speedily. Nevertheless when the Son of man cometh, shall he find faith on the earth?"
Since "christians" don't really ask, they'd answer, "Of course you will Genie, we are 2 billion christians in the world". Exactly, in the world; the real Thing takes you Out of it.
Would the Father send Jesus foreknowing that no one would believe in Him? No. What if He knew about only one who would believe? In this case, He would still send Him. If you were the only Faithful one in your generation, what would you do? Stand fast in the LINK or swap the real Connection, the illusory loneliness for the whole world and its "bond" and real forsakenness? Abandonment is a choice; you can choose to stop caring about every "thing" the unbeliever treasures to have ONE, or give in to weakness and leave Truth and yourself to be experienced only when you find someone else willing to come with you. Then, if your "life" becomes a horror movie, you should remember it was your choice to stay where evil dwells, resides, and "think" you your "self" were the most capable in the world of knowing about your own "happiness". However, to believe that seeking Truth is a waste of time is to be really alone and miserable, from beginning to end.
Do you have many "reasons" to stay? I'd go back only to rescue the ones who no longer have any.
There ain't no Good to be found.
