Jeremiah 1:17Meaning & Commentary from the Church Fathers

You are to engage in the same way. Collaborate with Me, assist Me. What does it mean to ‘gird up’? It is akin to how a doctor readies a disciple for a significant task; it is not merely a simple phrase to be spoken once or for a fleeting moment. It calls for courage because you have a great contest, a battle, and a war of considerable scale ahead of you. And rise up. This does not imply remaining seated (how could one remain passive in light of such sights and sounds?), but rather, stir yourself, elevate your focus on the words being spoken; you must give careful attention to both what I say and the message that is being imparted. Here, you need to remain vigilant, while there, you must be brave.

Do not be afraid in the presence of those whom you believed were orchestrating your demise.

Job is instructed to prepare himself, as seen in Job 4, while the apostles are similarly urged in Luke 12 to be equipped for service, echoing the readiness of Elijah (1 Samuel 4) and John the Baptist (Matthew 3), who donned leather belts. They are to hold in their hands the lamps representing the proclamation of the Gospel. Thus, anyone charged with conveying God's words must be spiritually prepared, recognizing that the devil’s influence lies in his loins, as Job 40 suggests, and that the righteous lament in the Psalms, "My loins are filled with chastisement" (Psalms 37:8).
