The word of God is inerrant. If even the fallen angels (demons) believe the word why can’t you? Read the word in James 2:18-19 :
But someone will say, “You have faith, and I have works.” Show me your faith without your works, and I will show you my faith by my works. 19 You believe that there is one God. You do well. Even the demons believe—and tremble!
And in Matthew 8:28 the demons immediately recognize Jesus as Lord and power over them:
28 When He had come to the other side, to the country of the Gergesenes, there met Him two demon-possessed men, coming out of the tombs, exceedingly fierce, so that no one could pass that way. 29 And suddenly they cried out, saying, “What have we to do with You, Jesus, You Son of God? Have You come here to torment us before the time?”
30 Now a good way off from them there was a herd of many swine feeding. 31 So the demons begged Him, saying, “If You cast us out, permit us to go away into the herd of swine.”
Believe that you may be saved.
