Just as our bodies need exercise to be strong physically, our faith needs exercise if we are to be strong spiritually. It has often been noted that several rivers flow into the Dead Sea, but no river flows from it.
That’s why its water has become so saturated with minerals over the centuries that nothing is able to live in it. Without any outlet it indeed has become a “dead” sea. The same is true with us. If we keep faith to ourselves, if we never allow it to flow through us to enrich others, and if it has no outlet, then we will find ourselves like the Dead Sea—lifeless and spiritually dead.
