Mt 1:1, Gen 3:15, Gal 3:16, 1 Jn 3:8, Gal 3:6-8,14
The Old Testament prophesied that Christ would come and break Satan's head. (Genesis 3:15)
Genesis 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.
God promised Abraham that Christ would come as Abraham's descendant. He also promised that the Christ would come and obtain the door of the enemy. (Gen 22:17-18)
Gen 22:17 That in blessing I will bless thee, and in multiplying I will multiply thy seed as the stars of the heaven, and as the sand which is upon the sea shore; and thy seed shall possess the gate of his enemies; 18 And in thy seed shall all the nations of the earth be blessed; because thou hast obeyed my voice.
Jesus is the Christ, the descendant of Abraham. (Mt 1:1, Gal 3:16)
Mt 1:1 The book of the generation of Jesus Christ, the son of David, the son of Abraham.
Gal 3:16 Now to Abraham and his seed were the promises made. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ.
Jesus is the Christ who destroyed the works of the devil. (1 John 3:8)
1 John 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.
Abraham was recognized righteous by believing in the coming Christ. Likewise, if we too believe that Jesus is the Christ, then he becomes a descendant of Abraham. (Gal 3:6-8,14)
Gal 3:6 Even as Abraham believed God, and it was accounted to him for righteousness. 7 Know ye therefore that they which are of faith, the same are the children of Abraham. 8 And the scripture, foreseeing that God would justify the heathen through faith, preached before the gospel unto Abraham, saying, In thee shall all nations be blessed. 14 That the blessing of Abraham might come on the Gentiles through Jesus Christ; that we might receive the promise of the Spirit through faith.
