God says, “From the words of God people come to understand God’s will, and from the work of God they come to know God’s disposition and what God is.…” God is the truth, the way and the life. What He expresses is the truth. The Bible isn’t a record of all God’s personal utterance but an account of God’s work. In the Bible, Jehovah’s words, Jesus’ words, and the words God revealed to the prophets are truly God’s words, and the rest are mostly the record of history and man’s experiences. The Bible only has a little part of God’s word, it’s too limit. We couldn’t know God or God’s work from the Bible alone, now God has returned and expressed many words, we can know more clear about God’s will, God’s work, God’s disposition and God Himself.
