the scriptures rock, but let’s also realize just as importantly:
1 Timothy 3:15:
“But if I should be delayed, you should know how to behave in the household of God, which is the **church of the living God, the pillar and foundation of truth.”**
John 10:30 I and my father are one.
That teed off some Jews let me tell ya!
It’s been said before, if all that had survived of the New Testament over the ages was the books of John and Romans we would still have all we need for a complete NT doctrine. You can’t beat them. It’s difficult to read John 6 and believe that Paul had probably never read it when he wrote Romans. Then you remember both had the same author.
This is a great example of why cherry-picking your verses is such a bad thing. Here's the entire sentence (of which you only quoted about half):
You search the Scriptures because you think that in them you have eternal life; and it is they that bear witness about me, yet you refuse to come to me that you may have life. (John 5:39-40)
The basic sense of the entire sentence is different from what you're saying. Jesus is talking about how one achieves eternal life -- it comes from having a relationship with Jesus, not through book learning.
To make the context absolutely clear, Jesus is talking about the Old Testament in this passage. And it certainly does bear witness about Jesus. The OT was not the only way that people knew about Him at the time, however, nor after His death and resurrection. After all, John's Gospel wasn't written until much, much later -- and yet people came to Know Christ just the same. You need to be careful about making such a broad claim.
I'll go further: Scripture is a great way to know about Christ, but that isn't the same as knowing Him. When Jesus referred to "coming to me," he meant it in the latter sense: to know him. If one only knows about Jesus from reading Scripture, I would suggest that he is still ignorant of Christ.
For people like us, "knowing Christ" depends quite a lot on the Holy Spirit....
