In Matthew, Christ calls us to be salt to the world. People of His, who give the world flavor, bring out the best in others. They are giving, humble, spiritually attractive and enhance the desireable while never taking credit for themselves.
He warns us against losing our saltiness. Salt was created for a purpose, just as we have been created for a purpose. We all have different "flavors", but we're all instrumentally important to God's overall, eternal plan.
It's important to know your gifts, your God-given abilities so you can play your part in God's ultimate plan f0r others as well as for yourself. My "saltiness" comes from my relationship to others and my creative gifts. I pray I use these gifts wisely and never hide behind a false modesty or any amount of pride. These gifts are what makes me a "salty-salt".
What makes you salty?
