In the 14th century, scientists discovered how to determine if a solution was acidic or alkaline based. The mixture of organic compounds used to indicate red for acid based solutions, and blue for alkaline, was called "Litmus". Today, we use the same term figuratively when determining the validity of someone, or something. As Christians, we have a "Litmus Test" for all things spiritual. We can test whether a spirit is from God, or from satan. Join us this Sunday for our sermon, "Spiritual Litmus Test," from 1 John 4:1-6.
