A good way of looking at it, that i've found, is that its 100% God and 100% human. Its the word of God written down, incarnated into words. However the writing was done by humans who have their own historical, spiritual and personal issues to deal with. Every one of the Gospel writers had their own focus, why, because they were different people. But it was the same God, the same Jesus.
Were you looking for something more theological? Or specific?
