Luke 8:18 Therefore take heed how you hear. For whoever has, to him more will be given; and whoever does not have, even what he seems to have will be taken from him.”

Hearing is so important that it affect our responses at all times to matters of life. You need to hear right if you will act right. In fact, balance has to do with hearing, this implies that the way we hear ultimately affect our faith life. So Jesus gave a warning: be careful how you hear. Look at the next statement, it shows that hearing determine our receiving and loosing. 

Your hearing is based on your perception. Mostly, we interpret things based on who we are and not what we hear. This is why it is important for you to view and judge words based on the word of God. That means you need to constantly study and listen to God's word so that your perception and interpretations are influenced by His word. 

Faith comes by hearing, but not just anything you hear, but God's word. The moment God's word become the lense of your judgement or perception, you begin to see possibilities. 

Colossians 3:16 Let the word of Christ dwell in you richly in all wisdom, teaching and admonishing one another in psalms and hymns and spiritual songs, singing with grace in your hearts to the Lord. The more reason you cannot afford to hang around just anyone except you are influencing and dominating the atmosphere with your belief system.
