In Fredric Brown's short thriller “Knock”, he wrote, “The last man on Earth sat alone in a room. There was a knock on the door.” Yikes! Who could that be, and what do they want? What mysterious being has come for him? The man is not alone.

Neither are we.

The church in Laodicea heard a knock on their door (v. 20). What Supernatural Being had come for them? His name was Jesus, “the First and the Last . . . the Living One.” His eyes blazed like fire, and His face “like the sun shining in all its brilliance.” When His best friend John caught a glimpse of His glory, he “fell at his feet as though dead” (1:14–18). Faith in Christ begins with the fear of God.

We’re not alone, and this is also comforting. Jesus “is the radiance of God’s glory and the exact representation of his being, sustaining all things by his powerful word” (Hebrews 1:3). Yet Christ uses His strength not to slay us but to love us. Hear His invitation, “If anyone hears my voice and opens the door, I will come in and eat with that person, and they with me” (Revelation 3:20). Our faith begins with fear—who is at the door?—and it ends in a welcome and strong embrace. Jesus promises to always stay with us, even if we’re the last person on earth. Thank God, we’re not alone.
