Then will appear in heaven the sign of the Son of Man, and then all the tribes of the earth will mourn, and they will see the Son of Man coming on the clouds of heaven with power and great glory. And he will send out his angels with a loud trumpet call, and they will gather his elect from the four winds, from one end of heaven to the other. (Matthew 24:30, 31 ESV)

I find this exciting, can’t fathom what it will be like but expectantly waiting for his return one day.
