“Now Saul was afraid of David, because the Lord was with him, but had departed from Saul” (1 Samuel 18:12, NKJV).
Satan envies and fears most those who have been with God in prayer and are determined to stand up and fight in faith. Satan fears even a small army of those who are girded up in faith for a fight. He cowers before those who are up on their feet and ready to resist.
Because he fears you, his design is to neutralize your fighting spirit.
