Thy Kingdom Come is a global prayer wave between the feasts of Ascension (13th May) and Pentecost (23rd May).
It is a time when Christians around the world are invited to pray for more people to know Jesus and answer the call to be his disciple. There are a collection of Catholic resources you can use on your own or with others in this time including: morning and evening prayer, praying with Our Lady resources, live streamed night prayer, resources to pray for those you know who aren’t followers of Christ, and more!
