" I smoothed Colton’s blanket across his chest and tucked him in snug the
way he liked—and for the first time since he started talking about heaven, I
intentionally tried to trip him up. “I remember you saying you stayed with
Pop,” I said. “So when it got dark and you went home with Pop, what did
you two do?”
Suddenly serious, Colton scowled at me. “It doesn’t get dark in heaven,
Dad! Who told you that?”
I held my ground. “What do you mean it doesn’t get dark?”
“God and Jesus light up heaven. It never gets dark. It’s always bright.”
The joke was on me. Not only had Colton not fallen for the “when it gets
dark in heaven” trick, but he could tell me why it didn’t get dark: “The city
does not need the sun or the moon to shine on it, for the glory of God gives
it light, and the Lamb is its lamp. "
