Christians do not deliberately sin. This text does not say the devil lives in the one who sins...
Scripture teaches the Holy Spirit indwells the believer upon belief.
You teach a false doctrine. You are a sinner.
James 3:1
Let not many of you become teachers, my brethren, knowing that as such we will incur a stricter judgment.
You have condemned the Church and the Christ. This also makes you a sinner.
Matthew 7:2
because the way that you judge others will be the way that you will be judged, and you will be evaluated by the standard with which you evaluate others.
You have lifted yourself up in pride. This also makes you a sinner.
1John 2:16
For all that is in the world, the lust of the flesh and the lust of the eyes and the boastful pride of life, is not from the Father, but is from the world.
You suppress the truth others filled with the Holy Spirit reveal to you, another show of pride.
1 John 1:8
If we say that we have no sin, we are deceiving ourselves and the truth is not in us.
Read the scripture below, and learn something.
(1 John 1: 8-10) “If we claim to be without sin, we deceive ourselves and the truth is not in us. If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness. If we claim we have not sinned, we make him out to be a liar and his word has no place in our lives.”
You need to see John was saying if one says he or she says they have never sinned they are liars.
If one is forgiven of all unrighteousness are they not then sinless? Could they then be liars if they say they are sinless?
John later says:
(1 John 3:3-9) “Surely everyone who entertains this hope must purify himself, must try to be as pure as Christ. Any one who sins at all breaks the law, because to sin is to seen Him or known Him. My children do not let anyone lead you astray’ to live a holy life is to be holy just as He is holy’ to lead a sinful life is to belong the Devil, since the Devil was a sinner from the beginning. It was to undo all that the Devil has done that the Son of God appeared. No one who has been begotten by God sins: because God’s seed remains inside him, he cannot sin when he has been begotten by God.”
(1 John 3:8) “He who does what is sinful is of the devil, because the devil has been sinning from the beginning. The reason the Son of God appeared was to destroy the devil's work”
John told us those who did not know God sinned and asked forgiveness and were forgiven, but once a person comes to know God he or she will not sin.
Scripture goes on to say that if a person who does know God uses their free will to sin there is no repentance for that person.
(Hebrews 10:26-31) “If, after we have been given knowledge of the truth, we should deliberately commit any sins, then there is no longer any sacrifice for them. There is left only the dreadful prospect of judgment and of the fiery wrath that is to devour your enemies. Anyone who disregards the Law of Moses is ruthlessly put to death on the word of two witnesses or three; and you may be sure that anyone who tramples on the Son of God, and who treats the blood of the covenant which sanctified him as if it were not holy, and who insults the Spirit of grace, will be condemned to a far severer punishment. We are all aware who it was that said: Vengeance is mine; I will vindicate his people. It is a dreadful thing to fall into the hands of the living God.”
(Hebrews 6: 4) “As for those people who were once brought into the light, and tasted the gift from heaven, and received a share of the Holy Spirit, and appreciated the good message of God and the powers of the world to come and yet in spite of this have fallen away it is impossible for that to be renewed a second time. They cannot be repentant if they have willfully crucified the Son of God and openly mocked Him.”
