Those were the words from a wise old evangelist to a young man surrounded by a society of increasing godlessness and wrong beliefs. They're apt for every age, and no less our own. Bold words from atheists and philosophers about our origins, destinies and everything in between will always be pulling us away from the Bible on which our faith rests. 

It is God's word we have learned, and in which we have firmly believed, and He Himself has persisted it for us. So let's continue in it.

(2 Timothy 3:14)
