How do we know that faith comes by hearing and not sight?

The Apostle Paul in Romans 10:17 states emphatically that 'faith comes by hearing, and hearing by the word of God.' This underscores the principle that spiritual understanding and belief are imparted through the preaching of Scripture, rather than through physical signs or wonders. Throughout the New Testament, examples are abundant of individuals who witnessed miracles yet remained in unbelief, affirming that visual evidence without the Spirit's revelation does not produce saving faith. Ephesians 2:8-9 further confirms this, teaching that it is by grace we are saved through faith, and this is not of ourselves; it is the gift of God.
