What does the Bible say about stubborn hearts?

Scripture teaches that stubbornness manifests in the refusal to heed God's truth, resulting in spiritual deafness. In Hebrews 3:17, we see that because of disobedience and hard-heartedness, the Israelites suffered God's judgment. This principle applies to all generations as they turn away from divine revelation, illustrating the gravity of a stubborn heart that rejects the gospel's message. Acknowledging this, believers are called to examine their hearts for any signs of stubbornness that may hinder their response to God.
