One thing we always look forward to is writing and receiving Christmas cards.
Perhaps we appreciate them even more now, since they are rare here in Japan. Christmas cards can remind us to pray for others. Whenever we receive one, we can pray for that person/family. Or even when reading them later we can again pray for them. As is says in James:
James 5:16 Confess your faults to each other and pray for each other so that you may be healed. The prayer of a righteous man is powerful and effective.
