Simple faith and trust is your part; the Lord’s part he never fails to fulfill. By faith draw close to the precious Sin-bearer, and then cling to Him by faith. Do not worry; this will not help the matter at all. Believe that Christ Himself rebukes the enemy, and that he can have no more control over you. Believe that Satan has been rebuked. When the enemy comes in like a flood, the Spirit of the Lord will lift up for you a standard against him.
