Whenever I go on a trip, I tend to pack more than I need. I'm notorious for packing a ten pound purse. With at least three theology books, a snack, way too many flavors of lip balm... well let's just say I don't like to be caught without the necessities. But there have been times when I hardly packed anything at all. That's always the worst. Believe me, sitting in the dentist office without a book is misery.
In life, it can be hard to plan ahead. What exactly will you need? Will you get married? What will your husband do for a living? What kinds of skills are you going to need? Will you have a special needs child? Will you live in the country or the city? There is no way to know the answers to these quesitons. But I can tell you, I don't want to be caught unprepared. While we don't know the specifics of our life ahead, we do know that in whatever circumstances lie ahead we will be called to act as Christians, and to walk in a manner worthy of the calling to which we have been called.
I think we young ladies too often have a very limited understanding of what life as a Christian will take. We all know that we are to glorify God, even in the most mundane tasks (like eating and drinking). But how do we know what glorifies God? Joshua Harris once defined glorifying God as "doing everything for Him, His way." While I think most Christians get the "doing it for Him" part, I think we have too limited a scope on what doing it "His way" really looks like.
There is a doctrine in theology called the doctrine of the "antithesis". This doctrine states that Satan, since the garden of Eden, has been constantly at war with God. On every front, in every detail, satan creates an alternative to the way God wants us to live. We are in warfare, day in and day out, whether we realize it or not. Do you know for whose side you are fighting? Are you saying one thing, while unknowlingly acting upon a philosophy of life contrary to God? This is what growing in sanctification is all about, Semper Reformanda, Latin for "always reforming" to the Word of God. The moment we are saved, we are given a new nature. But we have to learn to live in conformity to that new nature. All of our thinking, habits, customs, and traditions need to be reevaluated. To be sanctified is to learn, by the renewing of our mind, to grow more and more into our new nature; thinking God's thoughts after Him, loving what He loves and hating what He hates.
The more robust our theology grows, the more we will realize that God calls us to so much more than we ever imagined. There are so many topics to study! Just to whet your appetite, let's look at a few areas that young ladies will need to know about. Rather than being a comprehensive list, this is just a list of some of the topics you and your parents can talk about, and perhaps use as a springboard for creating your own plan for topics to study.
