The Archbishop of Canterbury has admitted the terror attacks in Paris made him "doubt" the presence of God.
Justin Welby said he was left asking why the attacks happened, and where God was in the French victims' time of need. He said he reacted with "profound sadness" at the events, particularly because he and his wife had lived in Paris.
Asked if these attacks had caused him to doubt where God is, he said: "Oh gosh, yes," and admitted it put a "chink in his armour."
A bombing campaign against Islamic State was launched after the events, but the Archbishop warned against a potentially damaging instant reaction.
"Two injustices do not make justice. If we start randomly killing those who have not done wrong, that is not going to provide solutions. So governments have to be the means of justice.
"The Bible tells us that they are put there by God with the sword for justice, but they also have to lead us into a place where peace can be established. Religion is so powerful in the way humans behave that it has always been a tool used by the wicked to twist people into doing what they want them to do.
"But just because someone believes something deeply wrong does not mean that they are right in some way because they put God in it. The perversion of faith is one of the most desperate aspects of our world today."

The Archbishop of Canterbury, The Most Rev Justin Welby, was due to give his Christmas Day message today, but had to cancel due to illness.
The full text of the Archbishop's address has been published on www.archbishopofcanterbury.org, Lambeth Palace said.
He had been due to talk about how the true spirit of Christmas cannot be captured in fairytale endings, using the example of the First World War Christmas truce in 1914.
The Archbishop had been due to say: "The truce illustrates something of the heart of Christmas, whereby God sends his Son, that vulnerable sign of peace, to a weary war-torn world.
"The problem is that the way it is told now it seems to end with a 'happy ever after'.
"Of course we like Christmas stories with happy endings: singing carols, swapping photos, shaking hands, sharing chocolate, but the following day the war continued with the same severity.
"Nothing had changed; it was a one-day wonder. That is not the world in which we live, truces are rare."

Don't let the pressure of a perfect Christmas ruin your day.
It's perhaps what you expect the Archbishop of Canterbury to say, but Justin Welby is talking from personal experience.
Growing up, Christmas time was memorable for all the wrong reasons. It's just one of the things he spoke to Sangeeta about when she met the spiritual leader of the Church of England at Canterbury Cathedral.
"Don't let the pressure of having a perfect Christmas ruin your day", is the advice of the Archbishop of Canterbury as we all countdown to the big day.
At 6pm on ITV Meridian, we will have a special interview with Archbishop Justin Welby.
He will be talking to Sangeeta about some of the big issues that have defined 2014 and share some very personal memories from his childhood.
He will discuss spending Christmas with his father, who was an alcoholic:
The new Bishop of Basingstoke has been consecrated by the Archbishop of Canterbury at Winchester Cathedral. Reverend Canon David Williams grew up in Uganda before becoming Vicar of Christ Church in Winchester in 2002.
The Archbishop of Canterbury said the Church of England still has a "long way to go" as he spoke of the scars and "hurt" suffered by campaigners in favour of women's ordination in the face of "knee-jerk" resistance to change.
The Most Rev Justin Welby said celebrations to mark the 20th anniversary of the ordination of the first women to the priesthood in the Church of England should not overlook the "costly grind" of those who fought for the change to take place.
In a sermon at a national service in St Paul's Cathedral to mark the anniversary, the Archbishop warned against "triumphalism" but said the ordination of women should be celebrated with a "fullness of heart and no holding back".
