The Archbishop of Wales will use his Easter message to urge people "not to be afraid" in the face of terror attacks taking place around the world.
Dr Barry Morgan will also encourage people not to return "violence with violence" but to exhibit the Christian values of "forgiveness, compassion, mercy and grace" in the face of fear.
He will acknowledge growing concerns that Europe is being "inundated" by refugees, but will say "not being afraid means resisting all that enslaves, degrades and dehumanises" others.
Our world seems to be gripped by fear - to begin with there are constant threats of terrorist attacks on virtually every major city across the world.
Dr Morgan will also call on people to "value those who are least valued in society".
"Not being afraid means resisting all that enslaves, degrades, and dehumanises another human being and doing so non-violently", he will say.
The Archbishop of Wales will speak at a service at Llandaff Cathedral at 11am on Sunday.
