In the history of Christianity, two practices stand out as key elements of spiritual growth: prayer and Bible study. Fasting and meditation have also been important, for they support prayer and study. These are not chores to do so we can fulfill our "duty." Rather, they are a way of letting God conform us to the image of Christ as we "hang out" with him. See Our greatest needs: prayer and study by Joseph Tkach
Perhaps you want to read the Bible, despite its difficulties, because you have heard that it can tell you more about the God who made you and who loves you. It can tell you about Jesus, your Savior, and what he did and taught. There's treasure hidden somewhere in this book, but you aren't quite sure how to go about finding it. Here are Five simple rules for Bible study
Faith is an important part of Christianity — an essential part. But not just any faith will do — our faith must be in something that is true. Faith must not be a blind hope — it must be based on evidence. And evidence needs to be taught. The church Jesus founded is to be a teaching church, and his people are to be people who are learning.

"I don't want to study doctrine," one person said. "I'm tired of doctrine. I want sermons to be short and inspiring — I don't want them to be doctrinal." I can understand the feeling. Doctrinal arguments can certainly be wearisome, and doctrine can turn people off. Yet we still need doctrine if we want to understand our faith. A "doctrine" is a "teaching," and the important teachings of the church are those relating to truth about God. See The importance of doctrine
