Spiritual warfare ability of spiritual warfare believers

In the spiritual war, believers can't defeat Satan's actions on their own. Believers can only "do everything by the one who gives me strength." (Phil. 4: 13) Jesus Christ himself declared, "Without me, you can do nothing." (John's Gospel 15:5) It can be seen that believers are useless without the Lord Jesus Christ, especially in spiritual wars. What Christians need most in fighting Satan is courage and morale. With Jesus Christ as the marshal and Jesus Christ as the backing, as Christian soldiers, we have the courage and morale to fight Satan.
