When my husband and I moved to Seattle to be near his sister, we didn’t know where we would live or work. A local church helped us find a place: a rental house with many bedrooms. We could live in one bedroom, and rent the others to international students. For the next three years, we were strangers welcoming strangers: sharing our home and meals with people from all over the world. We and our housemates also welcomed dozens of international students into our home every Friday night for Bible study.

God’s people know what it means to be far from home. For several hundred years, the Israelites were literal foreigners—and slaves—in Egypt. In Leviticus 19, alongside familiar instructions like “Respect your mother and father” and “Do not steal” (vv. 3, 11), God reminded His people to empathetically care for foreigners, because they knew what it was like to be foreigners and afraid (vv. 33–34).

While not all of us as followers of God today have experienced literal exile, we all know how it feels to be “foreigners” on earth (1 Peter 2:11)—people who feel like outsiders because our ultimate allegiance is to a heavenly kingdom. We are called to create a community of hospitality—strangers welcoming strangers into God’s family. The hospitable welcome my husband and I experienced in Seattle taught us to extend welcome to others—and this is at the heart of being the family of God (Romans 12:13).

Our children needed a little coaxing to believe that it was worth putting on snorkeling gear to peer beneath the surface of the Caribbean Sea off the shore of the island of Tobago. But after they dove in, they resurfaced ecstatic, “There are thousands of fish of all different kinds! It’s so beautiful! I’ve never seen such colorful fish!”

Because the surface of the water looked similar to freshwater lakes near our home, our children could have missed the beauty hidden just below the surface.

When the prophet Samuel went to Bethlehem to anoint one of Jesse’s sons to be the next king, Samuel saw the oldest son, Eliab, and was impressed by his appearance. The prophet thought he had found the right man, but the Lord rejected Eliab. God reminded Samuel that He “does not look at the things people look at. People look at the outward appearance, but the Lord looks at the heart” (1 Samuel 16:7).

So Samuel asked if there were more sons. The youngest boy wasn’t present but caring for the family’s sheep. This son, David, was summoned and the Lord directed Samuel to anoint him.

Often we look at people only on a surface level and don’t always take the time to see their inner, sometimes hidden, beauty. We don’t always value what God values. But if we take the time to peer beneath the surface, we may find great treasure.
