Apply every word of Jesus Christ to every whit of your life and leave no corner of your life where the word of Christ is unapplied.
The words of Jesus Christ have been sealed by the blood of the Lamb of God and every part of your life where the word of Christ is applied is made pure by the atonement of the blood of Christ.
But every part of your life where words of Christ has not been applied the purifying power of God has not yet been applied; and in that part of your life Satan is free to roam.
Therefore any part of your life, whether it be your family, business, money, conversation and so on; where the word of Christ is not applied will be forcibly taken over by Satan.
But in that part of your life where the word is applied Satan cannot touch.
Therefore commit your whole life to Christ.
