Imagine that you are looking at a luxury liner moving through calm waters. To your amazement about a dozen people jump off the ship, and cling to a lifeboat. You watch as the rest of the passengers stand on the ship and laugh at them.
You can understand their reaction. What those few people did was foolish. It made no sense. Suddenly, the ship hits an unseen iceberg and sinks, taking with it all who stayed on board. Now you see that those who seemed like fools were wise, but those who stayed on the ship and seemed to be wise, were fools.
We have in the Bible a command to jump off the luxury liner of this world. Before you laugh at stupid Christians, ask yourself if there is any proof that its claims are true. I would suggest that you take the time to read the Gospel of John, with a humble heart.
