Why should Christians not fear according to the sermon?

The sermon emphasizes that fear should not plague believers because they dwell in the presence of the Most High, who is in control of all events. With references to Psalm 91, it’s made clear that God’s presence offers protection and that He has given assurance of care for His children. In tumultuous times, the promise of dwelling in Christ's security, knowing that He reigns supreme and that nothing can separate them from His love, instills peace instead of anxiety. Thus, believers are called to rest in the comfort of God’s sovereignty.
