Jesus said in John 5:39, "You search the Scriptures because you think that in them you have eternal life; it is these that testify about Me."
The Jews were trying to kill Jesus because He was breaking their Sabbath laws and also calling God His own Father. Jesus begins to tell them about the many different witnesses to the truth of who He is. The witness of John, the witness of His works, the witness of the Father, and here, the witness of the Scriptures.
When talking about the Scriptures, Jesus is talking about the Old Testament. Instead of seeking life in the rules and regulations the Jews had added to the Law of God, Jesus tells them the Law points the people to Himself. True life is found in Jesus Christ and the Scriptures should direct us toward Him.
As I read through the Bible, I ask myself these three questions:
1. What does this passage tell me about God?
2. How does this passage show me Jesus?
3. How can I now live for the glory of God because of this passage?
If the Scriptures testify about Christ, then I need to read the Scriptures with this in mind. As I grow in knowledge of God and knowing Him through Christ, then this same message must go forth to those God has called me to lead and teach.
Do you have a specific Bible reading method you use?
