Why is it important to understand that faith never comes by sight?

The importance of recognizing that faith does not come by sight is foundational to a proper understanding of salvation. As stated in John 12:37-38, the witnesses of Jesus' miracles still did not believe, affirming that faith is not merely a reaction to what we see or experience. This is crucial because reliance on visible evidence can lead to false assurances. True faith is rooted in the unseen realities of God's promises and character. Therefore, Christians are called to believe in Christ based on His revelation and not on their circumstances or feelings, underscoring the need for a heart transformed by grace to trust in the Savior who cannot be seen.
