Our heavenly citizenship offers comfort and rest. The author of Hebrews describes Abraham and Sarah’s longing for a heavenly homeland.

They did not receive what was promised, but they saw it all from a distance and welcomed it....If they had longed for the country they came from, they could have gone back. But they were looking for a better place, a heavenly homeland. That is why God is not ashamed to be called their God, for he has prepared a city for them. (Hebrews 11:13-16) 

Nothing beats the feeling of coming home after a long flight or a grueling car ride. This longing increases the closer we get to home. What is it about home that brings us comfort and relief?
