God Helps Design a Better Submarine

Engineers who design vehicles to move through fluids face a quandary. A torpedo-shaped vehicle can move quickly and efficiently through a fluid like water, but it is difficult to maneuver precisely...

Saliva Is Nothing to Spit At

Malachi 4:2
But to you who fear My name the Sun of Righteousness shall arise with healing in His wings; and you shall go out and grow fat like stall fed calves.

Someday, instead of having to give a blood sample during your physical exam, the doctor might just ask you for a saliva sample. Saliva is an amazing fluid. Besides helping us moisten and digest food, saliva is able to speed healing and fight bacteria, fungi and viruses. Saliva is chemically almost identical to the clear part of your blood. It even has, in lesser concentrations, the infectious organisms found in your blood. Let's say, for example that you suddenly find yourself in a stressful situation. The level of the hormone cortisol will increase in your blood in response to the stress. Within 20 minutes, that increase will be evident in your saliva. This means that someday saliva tests may replace blood samples. In the United States, saliva tests have been approved to diagnose AIDS, illegal drugs, periodontal disease, alcohol and premature labor. If the hormone estriol rises in a woman's blood before 36 weeks of gestation, doctors know that the woman may go into labor prematurely. Saliva testing is also used to check hormone levels in women who are having a difficult time conceiving a child. Other countries have approved a saliva test for hepatitis B.

Saliva's remarkable abilities are a witness to a loving Creator. He knew that we would sin and thus bring disease into the world. So He gave us saliva that not only defends us against infection but also helps us heal. But the greatest love He has shown us is in sending His Son to give us spiritual healing.

Prayer: 
I thank You, Lord, for all Your good gifts, especially salvation. Amen.
