And these are the ones by the wayside where the word is sown.  When they hear, Satan comes immediately and takes away the word that was sown in their hearts.  These likewise are the ones sown on stony ground who, when they hear the word, immediately receive it with gladness;  and they have no root in themselves, and so endure only for a time. Afterward, when tribulation or persecution arises for the word’s sake, immediately they stumble.  Now these are the ones sown among thorns; they are the ones who hear the word, and the cares of this world, the deceitfulness of riches, and the desires for other things entering in choke the word, and it becomes unfruitful.  But these are the ones sown on good ground, those who hear the word, accept it, and bear fruit: some thirtyfold, some sixty, and some a hundred.
(Mark 4:15-20)

The Bible tells us, that when a Christian believer starts feeding on and receiving the Word of God in their heart, that the devil will come immediately with what?  Cares, persecutions, trials and the desire of other things.  In other words, the devil comes to steal the Word of God out of your heart before it can take root and reproduce the flow of the divine mighty power of God in and out of you to this world.  Once a person has the revelation of who God Almighty is and how big Jesus is in you!  Then a Christian Believer can change and release the power of God to the world!  So the devil will come at you with everything he can, to get you to doubt your self.  A Christian thinks in their mind, “I must have a secret sin.”  “Why are all these bad things happening to me?”  “There must be something wrong in my life.”  “Maybe I haven’t done enough for God?”  When all the time, the Bible tells us that the devil comes against the Word of God inside of you with cares, the desires of other things and persecutions.  All these things are sent to steal God’s Word out of you!  You have to get heart and eyes on how big Jesus Christ lives in you!  All that God Almighty wants you to do is to trust, rely and love Him, that is what faith in the Word of God is to trust and to rely on God Almighty.
