Revelation 22:20 (KJV), “He which testifieth these things saith, Surely I come quickly. Amen. Even so, come, Lord Jesus.”
NO one knows when the Lord shall return but He is coming back riding on the clouds.
He will come at an hour when you do not expect him.
Some people used to say they thought people were being carefully warned about the flood during Noah’s time while that ark was being built. Matthew 24 v 39 tells us this, “and they knew nothing about what would happen until the flood came and took them all away. That is how it will be at the coming of the Son of Man.” (NIV)
