In my book The Purity Principle, I write about how God’s guardrails are His moral laws. They stand between us and destruction. 

When it comes to spiritual disciplines, some people think being committed to them is a matter of legalism. 

When the summer started, our grandsons weren’t having all that much fun in our big side yard. Why? Because there’s a road on the north side of our yard, and these days the cars present a real danger to careless children chasing balls. And our grandsons love to chase balls.

We live in the same house that we did when our daughters were small. Now they're grown and we have four grandsons. All those years our daughters were growing up, we never built a fence in our yard. There was no need.
