1. Christ who destroyed our enemies (Deut 32:43)
    1 Jn 3:8, Rom 16:20, Rev 12:12, Rev 19:2, Col 2:13-15

In the Old Testament it was foretold that God would destroy our enemies and forgive our sins. (Deut 32:43)

Deut 32:43 Rejoice, O ye nations, with his people: for he will avenge the blood of his servants, and will render vengeance to his adversaries, and will be merciful unto his land, and to his people.

As prophesied in the Old Testament, Christ destroyed the work of our enemy, the devil, by dying on the cross. (1 John 3:8, Col 2:13-15)

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.

Col 2:13 And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened together with him, having forgiven you all trespasses;
14 Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross;
15 And having spoiled principalities and powers, he made a shew of them openly, triumphing over them in it.

God will destroy Satan forever. (Rom 16:20, Rev 12:12, Rev 19:2)

Rom 16:20 And the God of peace shall bruise Satan under your feet shortly. The grace of our Lord Jesus Christ be with you. Amen.

Rev 12:12 Therefore rejoice, ye heavens, and ye that dwell in them. Woe to the inhabiters of the earth and of the sea! for the devil is come down unto you, having great wrath, because he knoweth that he hath but a short time.

Rev 19:2 For true and righteous are his judgments: for he hath judged the great whore, which did corrupt the earth with her fornication, and hath avenged the blood of his servants at her hand.
