“Ye are the salt of the earth, but if the salt have lost His savor, wherewith shall it (the earth) be salted? It is thenceforth good for nothing, but to be cast out and be trodden under the foot of men.” (Matt 5:13)
If the Christian fails to answer this calling, how will the world be salted: that is spiritually influenced? Salt is a seasoning which enhances flavor. The Christian may “season” by example and influence. Salt also purifies. In ancient times, salt was used in medicine. In the Old Testament, salt was required in every sacrifice. Also, a covenant of salt signified an everlasting covenant.
Salt symbolizes purity, perfection, wisdom, fidelity, and durability. Most importantly, salt works as a preserver. Imagine that the Christian influences were removed from the world. Who would preserve morality? Who would contend for peace and truth? It is the Christian influence that has preserved principles of godly living and the necessity of law and order. The Christian influence is a vital part of society.
The last part of Matt 5:13 presents the challenge for the Christian to be salt that retains the savor (likeness ) of Christ. The taste of godliness refreshes the soul in a land of sin where many need to: “Taste and see that the Lord is good: blessed is the man that trusts in Him.” (Psalm 34:8)
