I read the The Imitation of Christ by Thomas a Kempis. He wrote the book in the early 1400's. I enjoyed reading the few pages from it. Everything written in it was solid and true. The biggest take-away I got from the reading was, "We ought not to ask who is speaking, but mark what is said. Men pass away, but the truth of the Lord remains forever." This is just soo true. I mean the words and wisdom he shared 600 years ago was all truth from God, and it is truth that is still being taught, discussed, and read today. God's word has and will remain forever! Truth doesn't pass away.
I encourage you to read, or even skim the passage. I'll definitely come back to it.
