You are always in a chapter of Grudem's Book "Bible Doctrine". A chapter a week-ish.
Another great resource to have is Pocket Dictionary Theological Terms by Stanley Grenz.
Think about a "side" book you can read (in addition to one chapter a week-ish from Grudem's theology book) that will grow you in certain areas.
