Their mission was to contend with those who previously dominated the earth, including the malevolent powers that had claimed dominion over all creation and misled those made in the image of God into idolatry. The purpose of the divine disciples was to bewilder these powers, guiding those lost in deception to the light of truth and enlightening those enveloped in darkness; those who had once venerated such entities were transformed into genuine followers of pursuits that reflect holiness.
Consequently, it is fitting that He instructed them to carry nothing with them, wishing for them to be devoid of earthly concerns, free from worldly burdens to the extent that they would not even fret about essential nourishment. It is clear, then, that His command to refrain from such necessities is aimed at severing their attachment to wealth and material gain. He asserts that their honor, their very reward, lies in the absence of possessions. He distances them from even the essentials, instructing them not to take with them a staff, a bag, bread, money, or even an extra coat. Thus, as stated, He liberates them from vanity and the worries of the flesh, urging them not to be anxious about food, echoing the sentiment from the Psalm: “Cast thy care upon the Lord, and He shall feed thee.” It is indeed true, as Christ stated, “Ye cannot serve God and mammon.” Additionally, “For where your treasure is, there your heart will be also.” Hence, to facilitate a life of integrity and simplicity, free from vanity and unnecessary concerns, allowing them to wholly dedicate themselves to the proclamation of His mystery and labor tirelessly to convey the message of salvation to all, He instructs them to be unconcerned about clothing and sustenance.
The Saviour further instructs, “For let your loins be girded,” and “let your fires burn.” The girding of the loins symbolizes a readiness of mind for every good work, while the burning of lamps signifies the illumination of the heart with Divine light. Similarly, the Law of Moses explicitly instructs those who partook of the lamb, “So shall ye eat it: your loins shall be girt, your staves in your hands, your sandals on your feet.” Thus, it is important to recognize that those who embody Christ, the true Lamb, ought to be like travelers prepared for a journey; they should “gird their feet with the readiness of the gospel of peace,” as the blessed Paul urged us, and be attired appropriately as travelers. For it is inappropriate for those entrusted with the divine message who seek to succeed in their mission to remain idle; they must consistently advance and strive, not in uncertainty, but toward a glorious hope. Even those who may have once succumbed to the enemy's hand, if they fight in faith for Christ, the Savior of us all, will ultimately receive an imperishable crown.
