Tobias, the son of Tobit, is on a journey with the angel Raphael, who is disguised as Azarias. During their travels, Tobias catches a fish, and Raphael instructs him to keep certain parts of it. Tobias's question about the purpose of the fish's liver, heart, and gall reflects a natural curiosity and a desire to understand the significance of these items. This interaction is a reminder of the value of asking questions and seeking knowledge, especially when it comes to spiritual matters.
The angel's guidance represents divine wisdom and the assurance that God provides for His people in unexpected ways. The fish parts are later revealed to have healing properties, symbolizing how God equips us with the tools we need, even if we don't immediately understand their purpose. This narrative encourages believers to trust in God's plan and to be attentive to His guidance, knowing that He often works through ordinary means to achieve extraordinary outcomes.
