Why does the Bible say we should not walk by sight?

The admonition to walk by faith and not by sight reflects the essence of Christian life, suggesting that believers must look beyond their circumstances to the eternal truths found in Christ. In 2 Corinthians 5:7, Paul emphasizes that walking by faith involves trusting in God's promises despite what we see. The implication is that reliance on physical evidence can lead to doubt and fear, while faith provides confidence in God's sovereignty and goodness, enabling believers to persevere through trials without being swayed by external pressures.
