Thou believest that there is one God; thou doest well: the devils also believe, and tremble. James 2:19
You here many people say “Just believe in Jesus and you’ll be saved” well what about the demons? They believe Jesus exist also but they are condemned to Hell. Why? Because being a Christian is more than just believing that Jesus exists
The demons have full knowledge about Jesus, think about that. Demons are fallen angels, they were there when God laid the foundations of the world. They knew Christ before humans ever existed, they know his Deity. Yet they rejected God because of their sin. They rather fulfill the temptations of their lust than serve the Living God
And, behold, they cried out, saying, What have we to do with thee, Jesus, thou Son of God? art thou come hither to torment us before the time? Matthew 8:29
Every time we see Jesus encounter demons throughout the gospels, they know exactly who He is. They know exactly the power Christ posses, yet they still rejected him. And notice they know their fate, they know the time will come for their eternal judgement into outer darkness.
Saying, Let us alone; what have we to do with thee, thou Jesus of Nazareth? art thou come to destroy us? I know thee who thou art; the Holy One of God. Luke 4:34
We see over and over, every time the demons come into the presence of Christ, they tremble! Why? Because they know all about Jesus. Don’t be like the demons, theres a difference between knowing about Jesus and actually knowing Jesus
There more about being a follower of Christ than just believing, have a personal relationship with Him. Even Jesus is your Lord (Master) listen to him, obey him, serve him, love him because he loved you first! Amen!
