Any committed Christian is capable of initiating a good conversation on a biblical text. In reality, your fears in this area of personal work betray two Screwtape-like lies that every Christian must resist. First, that gospel growth depends on us and on our abilities. This is simply not the case. Our proficiency in the Bible is not the final arbiter in seeing spiritual growth occur. The Holy Spirit can and does use timid people just like us. The second lie we fight against is disbelief—disbelief in the potency of God’s word. We need to be reminded that God does his work in his way, and it is his word that accomplishes whatever he desires in the world.
