What does the Bible say about seeking signs for faith?

In Matthew 16:1-4, Jesus rebukes the Pharisees and Sadducees for their demand for a sign, stating that a wicked and adulterous generation seeks after such signs. This illustrates that reliance on miracles or external signs to bolster faith undermines the authority of God's Word. The testimony of Scripture concerning Christ should be the foundation of our faith, not the spectacle of miraculous events. In Isaiah 7:10-14, King Ahaz was offered a sign from God but wisely refused, acknowledging that seeking such proof would test the Lord and reveal a lack of trust in His Word.
