I wasn't sure what missions organization to pray for today. I have one for tomorrow and something special for Christmas Day, but I exhausted my knowledge of missions organizations. So I googled "pray for missions." The second hit was for Overseas Missionary Fellowship.
Formerly China Inland Missions, OMF is a missions organization that focuses on reaching people in East Asia. They have over 1600 workers from over 30 countries. Flipping through their website, I noticed that every page has a different prayer point on the banner at the top. This is an organization with a strong emphasis on prayer. I like that! Their December prayer requests are listed here. You'll have to scroll down to the 23rd.
