Hearing the word of God and understanding the word is essential when you are called upon to perform what the word says. Faith is dependent on the word and understanding that word to perform it. But the devil comes to steal the word from your heart. If he can get you to doubt the words of God or its validity he has effectively stolen the word from your heart. But God wants to take you into his land of milk and honey to establish a stronghold of his word in your heart and life. He wants to bring you into himself. The words of God in my life gives me the advantage.
