Faith is a cornerstone of the Christian life, and this verse underscores its vital role. It speaks to the heart of what it means to be a follower of Christ: living not by sight, but by trust in God's promises. The righteous, those who are in right standing with God, are called to live by faith, which means relying on God's guidance and provision in every aspect of life. This reliance is not passive but active, requiring believers to step forward in confidence, even when the path is unclear.
The latter part of the verse serves as a warning against shrinking back, which can be understood as retreating in fear or losing faith. God desires His followers to be bold and courageous, trusting Him completely. This message is particularly relevant in times of trial and uncertainty, where the temptation to doubt or give up can be strong. By living by faith, believers align themselves with God's will and find strength in His presence, knowing that He is pleased with their perseverance and trust.
