You don't know, and you're weighing in on "The Second Coming," prophesy?
Joseph, as a "type" of Christ:
Acts 7:13 And at the second time Joseph was made known to his brethren; and Joseph’s kindred was made known unto Pharaoh.
So, just as Joseph, who was not recognized by his brethren when he first appeared to them, he was when he appeared again unto his brethren, "the second time," so will the anti-type, the Lord Jesus Christ, who was not recognized by the vast majority of His brethren when He appeared on earth, at "the second time," "The Second Coming," he will be recognized...
Hebrews 9:28 KJV so Christ was once offered to bear the sins of many; and unto them that look for him shall he appear the second time without sin unto salvation.
