The Word of God is Jesus and Jesus said that the Holy Spirit would lead us to all truth. He did not say that about the holy bible. I'm not saying that the Bible isn't important. The book itself is not essential but its truths are. God can and did teach people those truths without the book. For many hundreds of years Christians did not have bibles in their homes. How did they possibly make it? They had a real spiritual relationship with God.
Today we think "If I haven't read the Bible I can't possibly know God's heart." Do not beat yourself up about not reading the Bible as much as you think you should. As a child of God the words of God should never condemn you. The Bible in the Christian life is not meant to be used as, "I'll follow the rules in the book and then I will meet Jesus."
Hebrews 4:12 says, "For the Word of God is living and active and sharper than any two-edged sword, and piercing as far as the division of soul and spirit, of both joints and marrow, and able to judge the thoughts and intentions of the heart. And there is no creature hidden from HIS sight, but all things are open and laid bare to the eyes of HIM with whom we have to do."
The Word of God this scripture is talking about is Jesus not the Bible. & Jesus is certainly living and active. 1 Chronicles 28 says, "The LORD searches all hearts, and understands every intent of the thoughts."
To think that quoting scripture to someone is guaranteed to pierce to their soul is a false idea. The living God is the one who does this, you can not force it. It is His job to do. Jesus is the sword of the Spirit spoken of in Ephesians 6:17. Jesus is a life giving Spirit (see 1 Corinthians 15:45). The Word of God is the loving, present tense Jesus speaking to the heart.
A lot of churches will teach that the Christian life is about oughts, shoulds, musts, supposed tos, trying to live by the laws that God had put in place, coming up with and following principles and methods for Christian living. What all of that is really doing is looking at pages in a bible and looking at a historical figure for methods and rules. The reality of the Christian life is Christ in you right here and right now, we are in union with Him. We live not by methods, rules, and trying to replicate past happenings but by living right here, in the here and now, with Jesus Christ and His life living in us.
Paul gives us great insight into the value of knowing Jesus in Philippians 3:8,
"Yes, everything else is worthless when compared with the infinite value of knowing Christ Jesus my Lord. For his sake I have discarded everything else, counting it all as turds, so that I could gain Christ and become one with him. I no longer count on my own righteousness through obeying the law; rather, I became righteous through trust in Christ."
