Matthew 16:27-28

27I tell you all this because I, the Son of Man, will come back to this earth with God's angels. When I come, I will have the powerful beauty of my Father. I will see what each person has done on earth. Then I will pay them what is right.

28I tell you this: When I, the Son of Man, come with power, some people who are standing here will see me at that time. Before they die, they will see me begin to rule in my kingdom.’
