Bakht Singh emphasizes that Jesus calls His followers to be the 'salt of the earth,' highlighting the essential qualities of salt: it adds flavor, represents faithfulness, preserves, and symbolizes friendship. He explains that without Christ, the world is tasteless and that believers, like salt, are meant to bring joy and health to others. Singh encourages self-examination to determine if one is 'good salt' or has lost their savor, urging believers to embrace humility, mercy, and purity to fulfill their divine calling. He concludes by reminding that true salt brings comfort and joy to those around us, even in the face of persecution.
