Our position in this day and age is unique, because as writers, we can help to show others what truth truly is, and do so in a way that instills this view rather than pushes it. This advantage has been acted upon many times through history, by authors who give us an example of the way that they proclaimed the truth in their writings. G.K. Chesterton and C.S. Lewis are two authors who wove their writings with truth taken from God's Word in a time when the world was drifting toward a changing truth.
Although we may feel that our writing is small and insignificant, we can have an eternal impact and change the world by our telling of the truth that is true, that Jesus Christ is the only truth in the world!
"Jesus said to him, "I am the way, and the truth, and the life. No one comes to the Father except through me." John 14:6 (ESV)
