Hebrews 13:1-2 NIV
Keep on loving one another as brothers and sisters.  Do not forget to show hospitality to strangers, for by so doing some people have shown hospitality to angels without knowing it.
Judith Kerr wrote a famous children’s book about a surprise visitor, The Tiger Who Came to Tea. It would indeed be surprising to have a giant cat come for dinner, but even more surprising to discover you are playing host to an angel! However you understand angel in this verse, a supernatural visitor or simply a messenger for God, the point is clear, be welcoming to strangers because you never know who they might be, and how in doing so you are playing a part in God’s plan.
How should I respond to this strange verse Lord? Should I simply treat everyone as if they could be you or yours? Help me to find Christ in the face of friend and stranger.
