The Gospel of John fragment (8:14-22) from the 3rd Century
Why should we read our Bible? It's just a guide, isn't it? It's just a rule book, right? Wrong.
The answer is found in the book of John. In John 17:17 Jesus says, “Sanctify them...that is those who belong to Him in the world, believers...sanctify them in the truth. Thy word is truth.”
The Greek word aletheia is the word for truth. We Christians are sanctified ("made holy") in this aletheia. So, then, the key to being holy and pleasing to God is to know and obey the truth, and that is what the word of God is. Reading the Bible and getting into its depths is the doorway to holiness.
I had a talk with a young man this week who is desperately seeking to be a true, genuine Christian. He finds this authentic walk in holiness by going to the source of God's communication with us: the Bible.
