David trusted in God when he was afraid. Fear is a strong base emotion. David’s fear was not vague; it had tangible facts that awakened the feeling. Saul had tried to pin him to the wall with a spear more than once (1 Samuel 18:11, 19:10). Now King Saul sent out groups of men throughout Israel to find him. When afraid David cried out to God and trusted him.
Some people have fears that are more imaginary than real. For example, the fear of a dark night is based on the unknown. I may hear unknown noises and assume the worst. Fear grows with imagination.
Some have “what if” fears. For example, believing that if they leave their house something terrible will happen to them. They make assumptions based on nothing tangible and so stay in their house.
No matter if fear is based on facts or assumptions and imagination, fear can be overcome. Do I trust Jesus enough to face my fear and say, “No more! You will not have power over me anymore for my God is all-powerful.” As the Lord God told Joshua who was about to go into a mighty country with the small Israeli army, “Have I not commanded you? Be strong and courageous. Do not be terrified; do not be discouraged, for the LORD your God will be with you wherever you go.” (Joshua 1:9) Four times the Lord said that on that occasion. Repeat and believe.
