Only the Lord Jesus Christ can set you free from slavery to the sinful nature of the Devil in you. The only reason why there is no room for God's word to be formed in you is that; the sinful nature of the Devil has fully claimed ownership over it and you are fully its slave. All the rooms of your heart are filled with it. You could only do evil as a result and never could for a moment have good thoughts or desires in your heart. The sinful nature of the Devil have fully overcome you and therefore, all your actions are only misdeeds of that evil nature.
You can be freed from the sinful nature of the Devil in you and it will only be by the Word being formed in you. That Word is Jesus Christ, who is Word made flesh so that all flesh that obeys the Word will become like the Word with all His divine natures formed in them. Our sonship to God can only come through Christ our Lord because He is the Firstborn of God. All those who love and obey Christ will be re-created in His likeness. If we belong to Him, we will be like Him in everyway. If we don't, we will look like Adam with the Enemy of God filled in him.
Jeremiah 22:13-17
New International Version 1984 (NIV1984)
“Woe to him who builds his palace by unrighteousness, his upper rooms by injustice, making his countrymen work for nothing, not paying them for their labor. He says, ‘I will build myself a great palace with spacious upper rooms.’ So he makes large windows in it, panels it with cedar and decorates it in red. “Does it make you a king to have more and more cedar? Did not your father have food and drink? He did what was right and just, so all went well with him. He defended the cause of the poor and needy, and so all went well.
Is that not what it means to know me?” declares the LORD. “But your eyes and your heart
are set only on dishonest gain, on shedding innocent blood and on oppression and extortion.”
