Is it possible to live free from fear in this dangerous and unpredictable world? Yes, it most definitely is! Because protection is a solid promise of God.
But it's not a promise that's offered to just anyone. It is promised to those who abide in the Lord. To abide means "to dwell, to remain and to continue." To abide in the shadow of the Almighty is to live in continual union with Him, keeping His Word and obeying His voice. Those who abide in the Lord can live without dread of what the devil will do.
Let me make this clear though—God's promise of protection doesn't guarantee that the devil will leave you alone! It means that God will give you a way of escape every time the devil rears his ugly face at you.
If you are afraid of the dangers around you, spend more time in the Word and in prayer until your trust in God overcomes your fear. Draw closer to the Lord until you are abiding in the shadow of the Almighty and—no matter how dangerous this world becomes—He shall surely deliver you.
