Jesus will never return.
A poster once told me that, in his opinion, the Second Coming of Jesus would happen only when--through entirely natural causes--our planet be on the verge of destruction, and not before.
Well, I said, I am glad to hear that because, in that case, Jesus will never return because, soon after the Flood the Lord promised Noah that He would never again allow another universal destruction to destroy Mankind as long as the natural laws function properly. (Gen. 8:21,22)
Jeremiah read that text and said that as long as the natural laws function properly Israel will never cease as a People before the Lord forever. (Jeremiah 31:36)
Jesus must have read those two texts; the one of Genesis and that of Jeremiah and completed the info that salvation comes from the Jews as he meant universal catastrophe. (John 4:22)
Abraham went further and said that as long as there is a minyan of ten righteous, universal destruction would never happen. (Gen. 18:32) After all this, do you still think Jesus will need to come back? Hardly! Besides, Jesus' own gospel which was the Tanach, once dead, no one will ever return if you read II Samuel 12:23; Psalms 49:12,20; Isaiah 26:14; Job 7:9; etc.
