Salt of the Earth – Matthew 5:13
Pastor Tan Thai · Sep 18, 2011
This sermon based on Matthew 5:13 explores what it means for Jesus to call His disciples 'the salt of the earth.' Ordinary believers are called to live with a positive influence in a corrupted world, bringing the flavor of the Gospel and preserving society from moral decay.
The sermon opens with the context of the Sermon on the Mount, where Jesus proclaimed the Beatitudes to a crowd of Palestinians living under Roman imperial rule. The listeners expected blessings to come through wealth, power, and political freedom, but Jesus instead spoke of the poor in spirit, those who mourn over sin, and those persecuted for righteousness. He then made an even more surprising declaration: these very ordinary and lowly people are 'the salt of the earth' and 'the light of the world.'
Salt is common, inexpensive, and easy to find, yet it is absolutely indispensable. The sermon emphasizes that God does not use the wise, powerful, or noble, but chooses ordinary people to shame the wisdom of the world, as Paul confirms in 1 Corinthians 1:26-29. Biblical examples such as Moses tending sheep in the desert, David as the youngest son shepherding in the fields, Amos as a farmer, and the twelve disciples as fishermen and tax collectors all illustrate that God consistently uses ordinary people for His great purposes.
Salt has two primary functions: it gives flavor to food and preserves food from decay. Believers are called to bring a 'saltiness' to their words and lives that makes the Gospel attractive to those around them. At the same time, they are agents who slow down the moral decay of a world steeped in sin, from the fall of Adam and Eve through to modern evils such as human trafficking, war, and exploitation.
The sermon warns against two extremes. The first is the view that society will progressively improve through science, technology, and education without the need for God's influence. The second is the attitude of withdrawing from the world entirely, separating from society like monks in isolation. Salt is only effective when it makes direct contact with the food; likewise, believers must live within the world, participating in social, cultural, economic, and political life, as expressed in Jesus' prayer in John 17:15-19.
The sermon concludes by calling believers to be genuinely distinct in their daily lives, refusing to be secret believers who hide their faith. Speech, attitude, and conduct must reflect true transformation. The church must boldly speak the truth from God's Word, even when it offends, because truth — like the sting of salt on a wound — though painful, cleanses and brings genuine freedom.
