Do you find it hard to share your faith? How should we pray for other people - how do we actually evangelise?

These are some of the questions facing Christians today that we'll be talking to the Archbishop of Canterbury Justin Welby about live on Facebook this Sunday.

This will be the launch event for Facebook Live on Christian Today. We'll be asking him about his global call for Christians to pray this Pentecost for more people to know Jesus – called Thy Kingdom Come. If you have any questions about prayer, or about sharing your faith, post them in the comments and we'll put some to Archbishop Justin during the conversation.

You can also send questions to us on Twitter.

To watch live, just come to our Facebook page from 10am ET (or 3pm in the UK) and we'll be going live shortly after.

The Archbishop will be talking to Christian Today staff reporter James Macintyre and they will be joined also by Emma Buchan of Thy Kingdom Come, the #PledgetoPray global prayer event in May and June. 'I cannot remember in my life anything that I've been involved in where I have sensed so clearly the work of the Spirit,' the Archbishop says of this event. They will talk about evangelism, the central importance of prayer for Christians and what to do if you find it difficult to share your faith.

Sunday is Palm Sunday, the start of Holy Week. So they will also talk about the events that led up to the Crucifixion and the Resurrection of Jesus.
