“Ye are the salt of the earth.”—Matthew 5:13.
Salt is valued for its preservative properties; and when God calls His children salt, He would teach them that His purpose in making them the subjects of His grace is that they may become agents in saving others. The object of God in choosing a people before all the world was not only that He might adopt them as His sons and daughters, but that through them the world might receive the grace that bringeth salvation. Titus 2:11. When the Lord chose Abraham, it was not simply to be the special friend of God, but to be a medium of the peculiar privileges the Lord desired to bestow upon the nations. Jesus, in that last prayer with His disciples before His crucifixion, said, “For their sakes I sanctify Myself, that they also might be sanctified through the truth.” John 17:19. In like manner Christians who are purified through the truth will possess saving qualities that preserve the world from utter moral corruption. MB 35.2
Salt must be mingled with the substance to which it is added; it must penetrate and infuse in order to preserve. So it is through personal contact and association that men are reached by the saving power of the gospel. They are not saved in masses, but as individuals. Personal influence is a power. We must come close to those whom we desire to benefit. MB 36.1
The savor of the salt represents the vital power of the Christian—the love of Jesus in the heart, the righteousness of Christ pervading the life. The love of Christ is diffusive and aggressive. If it is dwelling in us, it will flow out to others. We shall come close to them till their hearts are warmed by our unselfish interest and love. The sincere believers diffuse vital energy, which is penetrating and imparts new moral power to the souls for whom they labor. It is not the power of the man himself, but the power of the Holy Spirit that does the transforming work. MB 36.2
Jesus added the solemn warning: “If the salt have lost his savor, wherewith shall it be salted? It is thenceforth good for nothing, but to be cast out, and to be trodden under foot of men.” MB 36.3
As they listened to the words of Christ, the people could see the white salt glistening in the pathways where it had been cast out because it had lost its savor and was therefore useless. It well represented the condition of the Pharisees and the effect of their religion upon society. It represents the life of every soul from whom the power of the grace of God has departed and who has become cold and Christless. Whatever may be his profession, such a one is looked upon by men and angels as insipid and disagreeable. It is to such that Christ says: “I would thou wert cold or hot. So then because thou art lukewarm, and neither cold nor hot, I will spue thee out of My mouth.” Revelation 3:15, 16. MB 36.4
Without a living faith in Christ as a personal Saviour it is impossible to make our influence felt in a skeptical world. We cannot give to others that which we do not ourselves possess. It is in proportion to our own devotion and consecration to Christ that we exert an influence for the blessing and uplifting of mankind. If there is no actual service, no genuine love, no reality of experience, there is no power to help, no connection with heaven, no savor of Christ in the life. Unless the Holy Spirit can use us as agents through whom to communicate to the world the truth as it is in Jesus, we are as salt that has lost its savor and is entirely worthless. By our lack of the grace of Christ we testify to the world that the truth which we claim to believe has no sanctifying power; and thus, so far as our influence goes, we make of no effect the word of God. “If I speak with the tongues of men and of angels, but have not love, I am become sounding brass, or a clanging cymbal. And if I have the gift of prophecy, and know all mysteries and all knowledge; and if I have all faith, so as to remove mountains, but have not love, I am nothing. And if I bestow all my goods to feed the poor, and if I give my body to be burned, but have not love, it profiteth me nothing.” 1 Corinthians 13:1-3 , A.R.V. MB 37.1
When love fills the heart, it will flow out to others, not because of favors received from them, but because love is the principle of action. Love modifies the character, governs the impulses, subdues enmity, and ennobles the affections. This love is as broad as the universe, and is in harmony with that of the angel workers. Cherished in the heart, it sweetens the entire life and sheds its blessing upon all around. It is this, and this only, that can make us the salt of the earth. MB 38.1
