Introduction: Evil deprives human beings of life, freedom, peace, and happiness, and it brings many kinds of mental and physical pain. Its final goal is to destroy one´s life. The devil is the root of evil, and the whole world is under his control. That is why this world is filled with pain. Ever since the time of Adam, humankind has been trying to gain freedom from evil, but with time, evil becomes more intense.


1. The cause of sin.
    1) Adam broke the law of God and acted as he pleased. The wages of sin is death
        (Ge 3:6).
    2) Adam listened to the devil, betrayed God, and became a slave to the devil.
        Since then, humankind has been in severe pain (Ge 3:17-19).
    3) By human power, it is impossible to take off the yoke of sin and evil (Eph 2:1-3).

2. Jesus´ public ministry.
    1) He forgave all our sins (Ro 3:23-24; Mk 10:45).
    2) He set us free from the pain that the devil brought.
        ① He drove out demons; the messenger of the devil (Lk 4:33-35).
        ② He healed physical and mental diseases (Mt 8:16-17).
        ③ He gave peace to those filled with insecurity, fear, and despair (Jn 14:27; 16:33).
        ④ He conquered death and raised the dead (Jn 11:25-26; 2Co 5:1).
    3) The redemptive suffering of the Cross.
        ① The judgment of God in regard to human sin (Jn 3:16-17).
        ② The evil spirit´s cruel attack (Jn 10:10; 1Jn 3:8).

3. It is finished.
    1) He forgave all our sins (Col 2:13; Eph 1:7).
    2) He disarmed the power and authority of the devil and took the pain away
        (Col 2:14-15).
    3) Deliver us from evil (1Pe 3:10-11; Pr 16:6).
    4) We must resist the devil, and drive out demons.
        ① We have authority (Lk 10:19; Jn 1:12).
        ② In the name of Jesus (Mk 16:17).
        ③ By the precious blood and the Word (Rev 12:11).


Conclusion : God´s will is to deliver us from spiritual, physical, and mental suffering into glorious freedom. Therefore, we must boldly resist the devil, and drive out demons.
