We’re born spiritually as babies just like our lives

“Then I looked, and there was a white cloud, and sitting on the cloud was what looked like a human being, with a crown of gold on his head and a sharp sickle in his hand. Then another angel came out from the temple and cried out in a loud voice to the one who was sitting on the cloud, 'Use your sickle and reap the harvest, because the time has come; the earth is ripe for the harvest!' Then the one who sat on the cloud swung his sickle on the earth, and the earth's harvest was reaped.”

— Revelation 14: 14-16

It’s the fulfillment of Matthew 24: 30 that says, “Then the sign of the Son of Man will appear in the sky; and all the peoples of earth will weep as they see the Son of Man coming on the clouds of heaven with power and great glory.”
