The Dead Sea is its name because it has no outlet. All minerals and salt remain. Water evaporates, but there is drain off. The resulting salt content kills virtually all life — no fish.

My awesome colleague, Tawnie Black, who gave up a high-paying, prestigious teaching job to help kids at the Lighthouse.
As a Christian, you are not designed to retain only. You must have an outflow of all you have learned in Christ, the love, the forgiveness, the good news. You can’t clam up. You must serve and give to others the blessings God has lavished on you.
If you bottle up the blessing, it will go rank (and I’m not talking about ranking with Google). It will spoil, sour, self-corrupt, go bad. Enjoy the blessings, but pass on the blessings. There can be no such thing as a selfish Christian. It simply does not exist.
A spring is known for what it gives. So too a Christian is only a Christian if he is like Christ, who gave the utmost. We must give finances for His work, time for service, and prayer for advancing the kingdom.
It is thought that Sodom and Gomorrah are buried under the Dead Sea. Not a good fate for a Christian. Our lifeblood is to share, give, and be unselfish.
