What does the Bible say about God's mercy for fearful believers?

In Judges 7, Gideon was called by God to lead Israel against the Midianites but was plagued by fear and doubts. God, in His mercy, reassured Gideon by confirming His promises through a sign, emphasizing that He understands our weaknesses and fears. As a Father comforts His children, God offers repeated confirmations to strengthen our faith, reminding us that His grace is sufficient for those who believe, and He does not rebuke us for our struggles. Psalm 103 highlights God's compassion, stating, 'As a father pities his children, so the Lord pities those who fear Him.'
