Most lighthouses are on the shore near rocks or dangerous places in the water. Practically all lighthouses seem to say, "Stay away from here. Danger!"
There is a lighthouse that says just the opposite, for it says, "Come!" This lighthouse is in the middle of the Arizona desert. There is no water to be had for over thirty miles in every direction, but just where that lighthouse stands there is a well. So there is a light there at night, to let thirsty people know where the well of water is. The tower in the daytime and the light at night say, "Here is water."
Isn't that just like the Lord Jesus who, in the midst of the desert of this world, would stand and cry, "If any man thirst, let him come unto Me, and drink."
Where else can you go for living water but to the Lord Jesus? The gospel is still offering to all, "Whosoever will, let him take the water of life freely."
Have you come to that life-giving water? Nothing else can satisfy soul-thirst, both now and forever.
