A ship at sea is where it was designed to be – in the water. But once water starts to get into the ship, if no action is taken, it is only a matter of time before the ship sinks. Although the ship is meant to be in the water, the water is not meant to be in the ship. As Christians, we are meant to be in the world, but the world must not be in us.

– Joel Beeke on Revelation 2:12-17 in Revelation
