What does it mean to live by faith according to Psalm 91?

Living by faith, as illustrated in Psalm 91, involves taking God's promises seriously and applying them to one's life. This faith is founded on God's Word, which reveals His character and commitment to His people. Christ demonstrated this faith as He lived in complete submission to God's will, relying on the truth of Scripture. For believers, living by faith means embracing the promises of God in all circumstances, recognizing that faith is nourished by understanding and meditating on His Word.
