Introduction
Many people consider the Bible an old book that has been endlessly copied. How do we know we can trust what it says?The first big translation was the Septuagint. But Jesus, Paul, and other New Testament writers quoted from it.Three sources of evidence
Jesus
Luke 4:14-21 – Jesus read from Isaiah 61:1-2, which was a messianic prophecy. Jesus called this passage scripture – God’s divinely inspired word. Were there copying mistakes in this scroll? Probably. But still, Jesus called it scripture.Peter
II Peter 3:15-16 – Note that Peter called Paul a beloved brother despite Paul previously sharply rebuking Peter for hypocrisy.I Peter 1:1 – Paul’s letters were all in wide circulation to all the churches by AD 70. Peter considered them equal to Old Testament scripture.Colossians 4:16 – Paul directed that his letters be copied and read by all.Paul
I Timothy 5:17-18 – Elders who rule well can be paid for their work. This is a quote from Luke 10:7. Paul quoted it and put it on par with Old Testament scripture.All of these quoted from old, likely flawed manuscripts and called them scripture.Conclusion
II Timothy 1:12
