Matthew 13:19 KJV
When any one heareth the word of the kingdom, and understandeth it not, then cometh the wicked one, and catcheth away that which was sown in his heart. This is he which received seed by the way side.
While most people will tell you they believe the Word of God is true, the vast majority of those who believe have also had that same word stolen from their hearts by the wicked one.
It is not the word of God that you believe; it is the Word of God that you keep and obey that operates in your life.

Our journey by faith is all about what we retain, not what we only hear. This is why it has no profit when the Word is not mixed with faith in obeying, keeping, and humbling ones self; it has no profit. To believe? Well, the devils believe…
James 2:19-20 KJV
There is one God; thou doest well: the devils also believe and tremble.  But wilt thou know, O vain man, that faith without works is dead?
When the word of God is spoken, it horrifies the enemy, and the army of evil sets out to steal it wherever it goes because it is the only weapon they recognize as effective against them. Such demons are witty and filled with schemes to cause the human race to write off God’s word as optional, outdated, and confusing. However, for Christians, the kingdom of darkness is more subtle.
They will use the Christian’s negligence against them.

The only way to avoid the wayside is to have such a prayer life that the Holy Spirit can guide you into truth and empower you to be obedient in your life choices.
