“You are the salt of the earth; but if the salt has become tasteless, how can it be made salty again? It is no longer good for anything, except to be thrown out and trampled under foot by men." ~Matthew 5:13
Conduct yourselves with wisdom toward outsiders, making the most of the opportunity. Let your speech always be with grace, as though seasoned with salt, so that you will know how you should respond to each person. ~Colossians 4:5-6
The gospel. Our testimony. Our stories of hope recording the miracles of God, His love, and His provision and protection. All of these in the hearing of our family, friends, and neighbors are for one purpose, to bring about a thirst for God.
Our words stir in others a desire, or for the sake of poetry and frankness, an ire. God's Word is a two-edged sword (Hebrews 4:12) "piercing as far as the division of soul and spirit, of both joints and marrow, and able to judge the thoughts and intentions of the heart." Your words, your answers, with regard to our King of kings has the power to make those who yearn for more search for Him.
Since our entire purpose is to point the way to Jesus, it make sense that we learn about Him more and more. Our words should be slathered in His grace, the salt, that others may want more of Jesus.
