Behold, he cometh with clouds; and every eye shall see him, and they also which pierced him: and all kindreds of the earth shall wail because of him. Even so, Amen. – Revelation 1:7
When Jesus comes, we will all know it. The people on the Earth, the people in Heaven and the people in Hell will see it. Every eye will see Him come in the clouds. Those who are His will rejoice. Those who aren’t will wail. Will you rejoice or wail?
