" This yields a practical help for Bible study: read the Bible with a red pen in hand. I suggest that you put a question mark in the margin beside every passage that you find unclear or hard to understand. Likewise, put an X beside every passage that offends you or makes you uncomfortable. Afterward, you can focus on the areas you struggle with, especially the texts marked with an X. This can be a guide to holiness, as the Xs show us quickly where our thinking is out of line with the mind of Christ. If I don't like something I read in Scripture, perhaps I simply don't understand it. If so, studying it again may help. If, in fact, I do understand the passage and still don't like it, this is not an
indication there is something wrong with the Bible. It's an indication that something is wrong with me, something that needs to change. Often, before we can get something right, we need to first discover what we're doing wrong. "
