There are rhetorical questions in Scripture. For instance, in Psalm 27, David asks, in light of the Lord in his life, “Whom shall I fear?. . .Of whom shall I be afraid?” (verse 1) David is making a statement in the form of two questions that imply a “No” answer: “I shall fear no one; I shall be afraid of no one.” It’s a powerful way to say, “Since I fear God, I will not fear man.”
If you fear (honor, respect, obey, worship) God, then you have a divine Protector. Why would you fear anyone or anything else?
The Lord is my light and my salvation; whom shall I fear? The Lord is the strength of my life; of whom shall I be afraid?
Psalm 27:1
