You are out, away from buildings, concrete, traffic and noise. Stars, crickets, and fireflies fill the night. Usually, tent camping is a blast until weather sets in. We find a tent flimsy, and weak.
"For we know that if our earthly house, this tent, is destroyed, we have a building from God, a house not made with hands, eternal in the heavens." 2 Corinthians 5:1
Your body is like a tent: it's temporary. After a while, the threads start to unravel, the flaps become more prominent, and it starts to leak. It's just the nature of this temporary body. Some people want to make their tent look like it's a brand-new model, younger than it really is. So they'll stretch the flaps, and nip and tuck, and dye the threads. You soon discover no matter how much fun, our bodies are not fit for long term tent camping.
When Christians leave earth we go to heaven. When we move from this tent, this physical body, we go to a permanent temple, a house. Our bodies are not meant to last. The tent will be taken down. In 2 Timothy 4:6 Paul said, "The time of my departure is at hand". In the Greek, the word departure means that it's time to take down the tent and move on. We trade in the tent for "a building from God,” our glorified, resurrected body.
There'll be a time when the tent will be taken down for something more permanent. Believers will receive a body fit to experience and enjoy everlasting heaven. We are only camping out here.
