Growing up in Minnesota, a place known for its many beautiful lakes, I loved to go camping to enjoy the wonders of God’s creation. But sleeping in a flimsy tent wasn’t my favorite part of the experience—especially when a rainy night and a leaky tent resulted in a soggy sleeping bag. I marvel to think that one of the heroes of our faith spent a years in tents. When he was seventy-five years old, Abraham heard God’s call to leave his country so the Lord could make him into a new nation (Gen. 12:1–2). Abraham obeyed, trusting that God would follow through on His promise.
