What does “His name shall be in their foreheads” (Rev. 22:4) mean?

Question:
In Revelation 22:4 when it says: ‘And His name shall be in their foreheads.’ What exactly does that phrase mean?

Answer:
The forehead often gives expression to what is inside the head. Joy and sadness can be seen on a person’s forehead. The above verse says that Jesus’ name (the Lamb) will be “in” their foreheads. In the soon coming day when we see Him face to face, we certainly will have Him on our minds and thus “in” our foreheads, and also we “shall be like Him; for we shall see Him as He is” (1 John 3:2)!
