Many people read the word as a story book and receive nothing, but have they studied under the direction and supervision of the Holy Spirit.
1 Corinthians 2:14 "But the natural man receiveth not the things of the Spirit of God: For they are foolishness unto him: Neither can he know them, because they are spiritually discerned".
Let's take a look at some specifics of the New Testament.
Anti-Semitism- Appears in Matthew, John, Acts, Romans, Corinthians 2, Thessalonians 1/2, Timothy 2, Titus, and Revelation.
Unbelievers fate in hell(whether or not they have ever been preached to about the savior)-
Appears in Matthew, Mark, Luke, John, Acts, Romans, Corinthians 1(Christians can judge anything and everyone, no non-christians can judge them 2:15), Corinthians 2, Galatians, Ephesians, Philippians, Thessalonians 1/2, Timothy 1/2, Titus, Hebrews, James, Peter 1/2, John 1/2, Jude and Revelation
Now this doesn't necessarily mean just a person that knows and understands god, and has simply not accepted him. It is explicitly clear that even if the word of god has never reached them through no fault of their own (because of geographic location, solitude etc..) they are still destined for an eternity of hell. To take it even further Jesus instructs his disciples to steer clear of certain groups of people (Gentiles, Samaritans) and go only to the Israelites(Matthew). This is a clear example of intolerance in the New Testament.
I'll end with this:
If anyone does not remain in me, he is like a branch that is thrown away and withers; such branches are picked up, cast into the fire and burned. John 15:1-8
This is a prime example of intolerance and unacceptance, stated in the New Testament, reminiscent of the Old Testament.
