what does the bible say?
The Bible meets or exceeds the standards of reliability used to evaluate other ancient documents. This is also, therefore, true of the New Testament. For example, many scholars place the New Testament writings to less than a generation after Jesus’ death, whereas many other historical documents are written hundreds or even thousands of years after the events they describe. Even those who date the New Testament writings later would place them before the destruction of the Temple in 70 AD since the New Testament doesn’t record that event.
Additionally, much of the New Testament is based on eyewitness accounts (Luke 1:1, Acts), such as when Paul indicated that the resurrected Jesus appeared to more than five hundred men, “most of whom” were “still alive” when Paul wrote his first letter to the Corinthians (1 Corinthians 15:6). Any of those witnesses could have come forward to dispute Paul’s claims about Christ’s resurrection.
Besides this, archeological evidence confirms the places and particulars of the New Testament. One such example is the Pool of Siloam where Jesus heals the blind man (John 9:1-11), uncovered in 2005. No archaeological discoveries have countered the New Testament accounts.
The apostles' willingness to face persecution and even death for Christ fruther attests to the trustworthiness of the New Testament (Acts 5:40-41; 2 Corinthians 11:23–28; Acts 12:1-2).
By any standard metric, the New Testament is trustworthy, meaning it is "God-breathed" (2 Timothy 3:16). Only those who deliberately suppress the truth will likely come up with reasons not to believe the New Testament is trustworthy (John 3:19).
