These are the signs that will be associated with believers: in My Name they will cast out devils; they will have the gift of tongues; they will pick up snakes in their hands and be unharmed should they drink deadly poison; they will lay their hands on the sick who will recover. (Mark 16:17-18)
The graces of binding and deliverance are special gifts which God has given us to destroy the power of the Evil One and to liberate those held captive in his power. It is through faith in Jesus Christ and by the power of His Name that the Apostles received the power to bind and cast out devils and spread the Kingdom of God. Evangelisation is a spiritual warfare against the powers of darkness that rule the world.
For it is not against human enemies that we have to struggle, but against the principalities and the ruling forces who are masters of the darkness in this world, the spirits of evil in the heavens. (Ephesians 6:12)
We are well aware that we are from God, and the whole world is in the power of the Evil One. (1John 5:19)
It is when the Word of God abides in us that we receive the spiritual power to overcome all the forces of darkness. (1John 2:14; 1John 4:4)
When Jesus sent His Apostles to evangelise the whole world, he sent them out with authority and power over all evil spirits and to bind and cast out devils. (Luke 9:1; Matthew 18:18)
But if it is through the finger of God that I drive devils out, the Kingdom of God has indeed caught you unawares. (Luke 11:20)
Through the grace of binding, God sends angels to bind the evil spirits and render them powerless at the word of the Apostles.
Or again, how can anyone make his way into a strong man’s house and plunder his property unless he has first tied up the strong man? Only then can he plunder his house. (Matthew 12:29)
And Raphael was sent to bring remedy to them both… and to rid her of Asmodeus, the worst of demons. (Tobit 3:17)
