Gen 3:15, Isa 61:1, 1 Jn 3:8, Mt 12:28, Lk 10:17-18, Col 2:15
The three major works of Christ are the work of king, prophet, and priest. Here we will look at the ministry of Christ as King.
In the Old Testament, it was prophesied that Christ would come to this earth and crush Satan's head. (Gen 3:15)
Gen 3:15 And I will put enmity between thee and the woman, and between thy seed and her seed; it shall bruise thy head, and thou shalt bruise his heel.
It is also foretold that Christ will come and set us free from Satan and sin. (Isa 61:1)
Isa 61:1 The Spirit of the Lord God is upon me; because the Lord hath anointed me to preach good tidings unto the meek; he hath sent me to bind up the brokenhearted, to proclaim liberty to the captives, and the opening of the prison to them that are bound;
Jesus came to this earth as the true King and destroyed the works of Satan. (1 Jn 3:8, Mt 8:32, Mt 12:28, Lk 10:17-18, Col 2:15)
1 Jn 3:8 He that committeth sin is of the devil; for the devil sinneth from the beginning. For this purpose the Son of God was manifested, that he might destroy the works of the devil.
Mt 8:32 And he said unto them, Go. And when they were come out, they went into the herd of swine: and, behold, the whole herd of swine ran violently down a steep place into the sea, and perished in the waters.
Mt 12:28 But if I cast out devils by the Spirit of God, then the kingdom of God is come unto you.
Lk 10:17 And the seventy returned again with joy, saying, Lord, even the devils are subject unto us through thy name. 18 And he said unto them, I beheld Satan as lightning fall from heaven.
Col 2:15 And having spoiled principalities and powers, he made a shew of them openly, triumphing over them in it.
Jesus also set us free from the law of sin and death. (Rom 8:2)
Rom 8:2 For the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death.
In other words, Jesus is the Christ, the true King who has broken the head of Satan.
