Psalm 11:1 In the LORD put I my trust: How say ye to my soul, Flee as a bird to your mountain?
The enemy can threaten all that he wants. He can tell us to run but we will not run. We will trust the Lord. We will believe God is going to take care of us and His ministry.
Fear and aggression are the tools of Satan. He tells us that there is nothing that we can do. He makes us think that we are defeated but we are not beaten. We have hope in the Lord Jesus Christ.
So when the fears and doubts attack you just answer like the psalmist and say that you will trust the Lord.
