In Matthew 6:16–24, Jesus calls us to examine what truly rules our hearts. Whether it’s fasting for show, chasing wealth, or trying to serve two masters, He reminds us that the condition of our hearts determines the direction of our lives. This passage challenges us to live with sincere devotion—seeking God’s approval, not the world’s applause—and to place our treasure where it lasts forever. When our eyes are fixed on the light of Christ, our lives reflect His kingdom values, not the world’s distractions.
