One of our Operation World team members was involved in the translation/creation of these prayer guides. Despite the tragic war, there are still many Russian & Ukrainian speakers in that region and around the world who would be delighted to know of these guides. As in English, they are to help Christians understand those worlds better, and to pray that people in those worlds will have a life-changing encounter with Jesus.
Do you know of believers who read Russian or Ukrainian? Then please point them in this direction for these free guides:
