What does the Bible say about Isaac's faith?

In Hebrews 11:20, Isaac's act of blessing his sons is cited as an exemplary expression of faith. He trusted in the Lord's promises, embodying the faith that Abraham also demonstrated. Despite the flawed circumstances of the blessing involving Jacob's deception, Isaac recognized God's sovereign choice of Jacob over Esau, emphasizing that God's purpose stands firm. This act of faith shows that true trust in God involves recognizing His sovereignty over human decisions and outcomes, illustrating that God's promises are fulfilled irrespective of human shortcomings.
