He warned, "But lay up for yourselves treasures in heaven, where neither moth nor rust destroys, and where thieves do not break in and steal." Heavenly treasures, which embody virtues, are both enduring and eternal; unlike earthly wealth, which provides only fleeting pleasure, these spiritual treasures accompany believers into everlasting life, granting everlasting joy. Conversely, the loss of earthly possessions brings sorrow, and their accumulation can lead to bondage, ensnaring the heart. The Savior articulated this truth: "For where your treasure is, there your heart will be also." He further illustrated the dangers of being ensnared by worldly desires through a vivid analogy: "The eye is the lamp of the body. If your eye is healthy, your whole body will be full of light; but if your eye is bad, your whole body will be full of darkness." He posed a question that underscores the gravity of moral decay: “If then the light that is in you is darkness, how great is that darkness!” Just as a damaged eye incapacitates the body, a heart consumed by greed darkens the soul, compromising its spiritual vitality. Another powerful teaching from the Lord highlighted the impossibility of serving two masters: "No one can serve two masters; for either he will hate the one and love the other, or else he will be loyal to the one and despise the other." The name Mammon, representing wealth, symbolized the pursuit of material riches among the Jews (Luke 16:9). Therefore, serving Mammon signifies an overwhelming obsession with wealth, overshadowing all other spiritual pursuits. St. John Chrysostom remarked, "If we serve Mammon, we cease to live under God's authority; being enslaved to wealth makes us captives, not merely to men, but to the most degrading passions and ailments of the soul." Nonetheless, according to this same Church Father, the righteous stewardship of wealth does not hinder service to God, as demonstrated by figures like Abraham and Job, who were not enslaved by their possessions but rather regarded them as gifts from God.
