What does the Bible say about faith being strengthened?

In Judges 7:9-15, we see God's encouragement to Gideon, demonstrating how faith is strengthened when one hears the word of the Lord. Gideon was instructed to go into the camp of the Midianites, where he would hear a reassuring dream that confirmed God's promise of deliverance. This act showcases the importance of God's word in instilling courage and faith in His people, illustrating that true faith is often bolstered during times of uncertainty. Just as Gideon's faith was strengthened by hearing God's message, believers today find their faith fortified through the preaching of the gospel, which declares what Christ has done for us.
