One of the ways that we build up our Faith in God and in his Word is by listening to God's spoken word. Faith comes by hearing and hearing the word of God.
For you to grow in Faith, it needs a continuous hearing of the word of God being spoken to you. The Word of God has to be communicated to you either through the inspired word of God from the Holy Spirit, listening to the audio bible, or listening to the word of God in Church.
What we hear affects what we believe and what we believe affects what we say and do. Your belief system is formed in 2 ways: From your experiences and from accepting what people have told you to be true
