It is a great misfortune that many evangelicals view spiritual growth in a very inorganic way. If a little boy wants to grow to be a great warrior, he needs to do three things: eat, sleep, & breathe. Many view spiritual growth in a very mechanistic way; as if to become more godly they need to add more hardware to themselves. But true growth in godliness comes through a few acts of obedience which spring from evangelical faith: read your Bible, say your prayers, and above all, worship the Triune God.
