No one can go to the gym and get in shape FOR you. If you want to get fit, you have to exercise yourself. The same is true when it comes to your spiritual growth. You will never become spiritually mature simply by listening to the pastor teach every Sunday. If you want to grow in Christ, you MUST pursue God yourself by regularly spending time reading His Word. The reward will be that you will hear God speak directly to you, and you will begin to grow spiritually mature.
