I am of the school of thought that believes the entire Bible canon of 66 books is "God-breathed".
I see no contradiction throughout the Bible as to God's nature.
I also see clearly that many of the things that non-believers attribute to God are not attributed to God in the Bible.
Many unbelievers and "believers", as pointed out previously in this thread, have taken things out of context, or choose to ignore entire portions of the Bible.
That is more than just a slippery slope. As has been pointed out, that approach allows one to pick their "favorite" parts and discard the rest.
The folks who say: "I don't agree with Paul's writings", "I don't believe the Genesis account", etc.
Those ones ought to simply admit they are making up their own God, and their own way to serve him.
So, what makes me, and other ex-jw's and other Christians I study with believe the entire Bible is "God-breathed"?
It starts with Faith, then daily prayer for His Holy Spirit, then daily Bible study.
The faith may start out tiny, like a mustard grain, but as one studies God's word under direction of His Holy Spirit, one begins to understand it's truth, it's reliability, what it doesn't and does teach. One discovers that it is indeed useful for teaching, for reproving, for setting things straight, that it is one of the primary ways God communicates to us personally. That in turn helps our Faith to grow. As Faith grows in God and His teachings, our eyes and mind continue to open, and we learn many new things everytime we read the Bible and apply it in our lives.
