Belgic Confession Article 12
He also created the angels good, to be his messengers and to serve his elect. Some of these have fallen from the exalted position in which God created them into everlasting perdition, but the others have by the grace of God remained steadfast and continued in their first state. The devils and evil spirits are so depraved that they are enemies of God and of all that is good. With all their might, they lie in wait like murderers to ruin the church and all its members and to destroy everything by their wicked devices. They are therefore by their own wickedness sentenced to eternal damnation and daily expect their horrible torments.
Then Satan answered the Lord and said, “Does Job fear God for no reason? Have you not put a hedge around him and his house and all that he has, on every side? You have blessed the work of his hands, and his possessions have increased in the land. But stretch out your hand and touch all that he has, and he will curse you to your face.” - Job 1:9-11
You [who deny that Jesus is the Christ] are of your father the devil, and your will is to do your father's desires. He was a murderer from the beginning, and has nothing to do with the truth, because there is no truth in him. When he lies, he speaks out of his own character, for he is a liar and the father of lies. - John 8:44
Anyone whom you forgive, I also forgive. Indeed, what I have forgiven, if I have forgiven anything, has been for your sake in the presence of Christ, so that we would not be outwitted by Satan; for we are not ignorant of his designs. - 2 Corinthians 2:10-11
And even if our gospel is veiled, it is veiled only to those who are perishing. In their case the god of this world has blinded the minds of the unbelievers, to keep them from seeing the light of the gospel of the glory of Christ, who is the image of God. - 2 Corinthians 4:3-4
