It is important to listen to what God says through the sermons, podcasts, books etc. but it is much more important to obey it. There are so many of us that know so much of the word and yet we do not apply it to our every day lives.
Lets be honest, we can measure the effectiveness of our Bible studies by the effect it has on our behaviours and attitudes. We need to receive deep into our hearts the truth of Gods word and let them to begin to work in our lives!
