Thy Kingdom Come is a global prayer movement which the Archbishop of Canterbury invited people around the world to join. The wave of prayer runs for 11 days between the Christian festivals of Ascension and Pentecost. During this time, people are asked to pray in whatever way they want and with whoever they want for others to come to know Jesus Christ.
