Can a Christian Have a Demon?
To answer the question, No! A Christian (any Christian) has more than one demon. The early church knew it, and after preaching the gospel and having people converted, they would pray for their healing and they would cast demons out of them.
And as you go, preach, saying, the kingdom of heaven is at hand. Heal the sick, cleanse the lepers, raise the dead, cast out devils: freely you have received, freely give. (Matthew 10:7-8)
We are spirit, soul and body. And the very God of peace sanctify you wholly; and I pray God your whole spirit, soul and body be preserved blameless unto the coming of our Lord Jesus Christ. (1 Thessalonians 5:23)
When we become born again, the spirit of God comes to dwell in our human spirit. Thus, our spirit is cleansed of all evil spirits that might have been there. This is why the born again experience. We feel renewed because the darkness in our spirit has departed and in its place the light of God has come in.
But our soul and body stay the same. We now can continue the process, in receiving in our soul and healing in our body. Some people stop at the born again experience of deliverance. Consider again the above Matthew scripture. The preaching of the Word comes first, and it brings the born again experience. But Jesus did not stop there. He said, besides that, to heal the sick, raise the dead and cast out devils. If the born again experience would have taken care of the diseases and the demons, he would not have said what he said.
Then Jesus went thence, and departed into the coasts of Tyre and Sidon. And behold, a woman of Canaan came out of the same coasts, and cried unto him, saying, Have mercy on me, O Lord, thou son of David, my daughter is grievously vexed with a devil. But He answered not a word. And his disciples came and besought him, saying, Send her away; for she cries after us. But he answered and said, I am not sent but unto the lost sheep of the house of Israel. Then came she and worshiped him, saying, Lord, help me. But he answered and said, it is not meet to take the children’s bread and cast it to the dogs. And she said, Truth, Lord, yet the dogs eat of the crumbs which fall from their master’s table. Then Jesus answered and said unto her, O, woman, great is thy faith: be unto thee even as thou wilt. And her daughter was made whole from that very hour. (Matthew 15:21-28. See also Mark 7:24-30)
a) Here is a woman that clearly was not from the children of Israel. This is why the disciples did not want to minister to her and wanted her to leave.
b) Her daughter had a demon, and the woman was pleading for deliverance.
c) Jesus did not even want to talk to her. When He finally talked, he said he came only for the Jewish people.
d) When the woman insisted, he said the woman wanted “the children’s bread”.
In other words, deliverance, which is what she wanted, was only for the children of God.
e) The woman’s insistence and faith in Him qualified her to be counted as a child of God, so she received her child’s deliverance.
If deliverance then, is for the children of God, then deliverance has been provided by God because it is needed. Christians do have demons.
