When fear attacks the believer, the real problem is not fear. Identify the core issue. It's a lack of faith in the sovereignty of God. Our God rules over all. Yes, our God rules in the affairs of men. When your faith gets hold of this, you become fearless. That the Most High rules in the kingdom of men (Daniel 4:17). Faith in the Most High God overcomes fear.
Moses was a Bible character, fearless because of his faith in God. By faith he forsook Egypt, not fearing the wrath of the king; for he endured as seeing Him who is invisible (Hebrews 11:27). He fulfilled his destiny, because he was fearless. He was able to do God's will, because he was fearless. He is an example for every believer today, who wants to walk in their God-given destiny to do God's will.
Overcome fear knowing that our God reigns! For of Him and through Him and to Him are all things, to whom be glory forever (Romans 11:36). Nothing comes your way, unless God allows it. He rules over all. Faith overcomes fear knowing who God is.
