What does the Bible say about seeking signs from God?

In Luke 11:29, Jesus addresses an 'evil generation' that seeks signs, indicating that such behavior reflects a lack of faith and spiritual insight. This attitude demonstrates a desire for tangible evidence rather than a reliance on the revealed word of God. Jesus further emphasizes that no sign would be given to them except the sign of Jonah, which points to the reality of His death and resurrection. Therefore, genuine faith is rooted in the acceptance of God's word and the work of the Holy Spirit rather than in miraculous signs.
