What does the Bible say about faith and deliverance?

Throughout scripture, faith is depicted not as a source of power but as a trust in God's sovereignty and deliverance. In 1 Samuel 26, David expresses confidence in the Lord to deliver him from tribulation. However, he also exhibits doubt in 1 Samuel 27, declaring he might perish at the hands of Saul. This reflects a common struggle among believers where they simultaneously trust God yet lean on their understanding and take actions contrary to that trust. Ultimately, true deliverance comes from God alone, as highlighted by David's experiences and reinforced in Romans 7, where Paul discusses the conflict between the will to do good and the presence of sin.
