The work of Christ is Salvation !2
Today in false christianity/religion, Christ's Work has been reduced to only accomplishing a possibility/ chance for Salvation, leaving it up to man to make it an actual experience.
The Death of Christ alone has effected into actualization the full Salvation of those He came to Save, His People Matt 1:21:
That includes Redemption, Reconciliation, Propitiation, and Justification, and Sanctification with final Glorification !
His Death was Authorized by God to save all for whom He died from the Penalty and Power of Sin, that's the meaning of Lk 1:71,74-75
71 That we should be saved from our enemies, and from the hand of all that hate us;
74 That he would grant unto us, that we being delivered out of the hand of our enemies might serve him without fear,
75 In holiness and righteousness before him, all the days of our life.
To be saved and or delivered from our enemies ! One of the Prime Enemies is satan, the Devil, an adversary 1 Pet 5:8
8 Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour:
Now the word adversary antidikos means opponent, enemy, The Devil is one of the enemies of the People of God, those made in His Image and Likness ! It was first seen with his attack against the first of God's People in Adam and Eve, they were the Church at that Time, the Body of Christ ! Thats why Paul uses that incident in counseling with the Church at Corinth 2 Cor 11:2-3
2 For I am jealous over you with godly jealousy: for I have espoused you to one husband, that I may present you as a chaste virgin to Christ.
3 But I fear, lest by any means, as the serpent beguiled Eve through his subtilty, so your minds should be corrupted from the simplicity that is in Christ.
That is evidence that he was an enemy of the People of God from the dawn of world history.
Now the devil, the serpent, satan is one of the enemies the people of God must be delivered from in order for Christ's coming to die and be our Salvation can be successful ! Lk 1:71
71 That we should be saved from our enemies, and from the hand of all that hate us;
Satan was the enemy of Adam and Eve and hated them for God's Image sake ! Now, will those He came to be Saviour unto, be saved out of his hand ?
