Commentators note that God's question, "Is there anything too hard for me?" is a powerful, rhetorical statement meant to build faith. It directly echoes Jeremiah's own declaration of faith from earlier in his prayer (v. 17). God isn't seeking an answer; He is affirming the truth of His own omnipotence to a prophet surrounded by a seemingly hopeless situation, reminding him and us that our faith in His power is well-placed.
