An empty soul is like a vacuum cleaner that sucks in the dust from the world's system of demons. Because the soul is empty, it receives worldly spirits and projections from the atmosphere, and begins to be conformed to the world. That is why it is necessary to keep the soul filled with God's Word.
Oh, what a privilege to have the love of Christ possess us on earth in three dimensions of time-to have that love pass all knowledge of my past and my sins. What a privilege it is to be filled with all the fullness of God so that He may do exceeding abundantly above all that we ask or think, according to the operational power and ability that works in us.
How can I remain filled with all the fullness of God? By continuing to hear the Word of God which produces faith (Romans 10:17). Faith comes from hearing the Word of God-not first from reading it, but from hearing it. Then immediately that faith gives me the grace to obey what I hear, because of the Holy Spirit's operation and divine ability. When I obey (as soon as I hear), my faith begins to serve others by the same love in which I've been rooted and grounded. There is a manifestation of love because of my obedience to the Word through the activity of faith.
