"For God has not given us a spirit of fear, but of power and of love and of a sound mind" (2 Timothy 1:7). It's not the will of God for us to be tormented by fear. The power of God's love gives us a sound mind. Pull down fearful thoughts in prayer, asking God to deliver you from them. Focus your attention on God's love. Believe in God's power to overcome fear in your life.
Understand fear for what it is, a spiritual problem. A spirit of fear may attack your mind with tormenting thoughts. Understand that you are in spiritual warfare. There is power available to conquer fear. It is the power of God's love. Understand that "God is love"(1 John 4:8). He can overcome any fear that comes your way.
Ask God to deliver you from fear. That's God's will according to God's love. He is able to deliver you. He will deliver you. Then, ask God to fill you with His love. He will, because that's who God is. The result will be the power of love overcoming the spirit of fear. God will give you a sound mind, focused upon His love for you.
Do you know someone who is troubled with fear. Share God's word with the person. Explain that God's word is God's will. Assure that person of God's love and power to deliver from fear. Have prayer with the person, asking God to deliver from fear and fill the person with love. You can make a real difference in a fearful person's life.
