 It might be a small sacrifice of you providing a meal for someone, or it might be a bigger sacrifice. You're providing a room for them to stay in rent-free, or you're providing them love and compassion and human closeness and something that maybe they've not experienced since they've been in your community or in your country or maybe in their own lives. They've not really experienced this before, and God's using you to show them that love, and that requires sacrifice on your part.
