If you are driving through mountains, you have to be careful because of the dangerous switchbacks. There are signs that tell you when the sharpest curves are up ahead. Not following those warnings is dangerous, if not deadly.
Or if you go swimming in the ocean, warning signs tell where there’s an undertow. Ignoring those signs can bring disaster.
When you have a prescription filled, the pharmacist sticks on a warning label telling you what and what not to take with your pills. The difference between heeding those warnings and not heeding them can be the difference between recovery and staying sick.
The Bible contains warning signs for living the Christian life that are to be taken seriously. They can mean the difference between eternal life and eternal death. Think of your Bible as having a warning sticker, “Ignore at your own risk.”
