If we want to grow spiritually, there are actions we must take.
We must be ever increasing in our faith and we know faith comes by hearing (the word). Spiritual growth happens when we are speaking the word, if you're not speaking the word, what are you speaking? 
     The only ability the enemy has is to steal the word from you, that is, if you let him. You have the ability to shut him down, to refuse to allow him to discourage you. How? With the word, but the word must first be in you, by hearing and speaking it.
