Revelation 22:4
Revelation 22:4 And they shall see his face; and his name shall be in their foreheads.
And they shall see his face
By seeing his face, we are to understand such manifestations and open visions of God in Christ, as the saints have in Heaven. Read 1 Corinthians 13:12; 1 John 3:1-3.
And his name shall be in their foreheads
See Revelation 14:1
