What does the Bible say about confidence in the gospel?

In Romans 8:31-39, Paul emphasizes the certainty of God's support for His people. He assures us that because God has not spared His own Son, we can be confident that He will provide us with everything we need for salvation. This confidence is rooted not in our abilities or feelings, but in God's immutable nature and His promises. Paul questions, 'If God be for us, who can be against us?' highlighting that true power and sovereignty belong to God, shielding us from condemnation and separation from His love.
