As a general comment, my personal experience shows that, almost without exception:
(1) those who object most strenuously to the Bible have never actually read it, and
(2) those who extract parts of scripture, frequently (and intentionally) do so to for the purposes of supporting a pre-determined position, frequently taking extracts outside of the original Biblical context - all with the intention of attempting to invalidate the entire Bible, not understand the scripture in question (if they cam make one thing look wrong, then they conclude that the entire thing must be wrong), and
(3) those who draw incorrect summaries fail to understand (and have no intention of understanding) the historical meaning of the terminology as it existed in Biblical times, and assign words and phrases a contemporary meaning.
The problem gets worse as others frequently rely on the misinterpretations and misstatements made by these self-appointed scholars and use them as the basis for their own beliefs. It is like the "telephone game", except that it starts from flawed conclusions from inception, and then becomes more mistaken over time.
Oh, and most of the time, references are made to the Old Testament, not to the new covenant.
The next time someone alleges that the Bible is full of conflicts and inconsistencies - ask them to give you a few examples. You are very likely to be rewarded by blank and confused looking faces. They "got nothing", because they have simply relied on generalized locker room legend created by those intended only to excuse themselves from being subject to God's laws. When I have heard others claim that the Bible is full of conflicts and inconsistencies, I have offered to help research the conflicts and have asked them to give me one or two areas that bother them the most. I have never had anyone respond with anything specific or tangible. The few responses I have received are usually something they "think" is in the Bible, but that is not.
Words and context have meaning. Ignoring them will always lead to erroneous conclusions.
