What does the Bible say about the significance of salt?

In Mark 9:50, Jesus states that 'salt is good' and emphasizes its importance in the lives of believers. Salt acts as a preservative, preventing corruption and decay, which reflects God's grace in sustaining and preserving His elect. Additionally, in Leviticus 2:13, every offering was to be seasoned with salt, signifying the covenant God made with His people through His grace. This illustrates that just as salt enhances flavor, God's grace is essential for true spiritual life and sustenance.
