How much knowledge of Scripture is enough?

I believe that after years of church going, one knows enough. Action is therefore key. Love and serve others as you would the Lord. That is my current stance. To me (protestant), pastors are historians. Once you know the ebbs and flows of the Bible, all the rest is reminding. Which is a good thing. Nonetheless, it is not enough, one must act. Love and serve. Am I wrong? I do value church, but I have Church. So, is there a point where going to church to learn is enough? I am guessing that church is more of a community of people striving for the same ideal. Refining oneself to love and serve better others as one would the Lord.
