Church Army is delighted with the impact being made by its Now a Christian email course.
So far, more than 3,000 people have taken part in the course, which aims to bring people to a living Christian faith.
The course - available at www.nowachristian.org - has been specially designed to help people explore the basics of Christianity.
After signing up for free, people will receive an email every day for five weeks allowing them to explore what it means to follow Jesus and make their own decisions about the Christian faith.
Here is some of the feedback Church Army has received from participants: "Thank you so very much for Now a Christian. Through it I have learnt, started to read my Bible, prayed, cried and tonight I opened my heart to God who I have rejected and been angry with for so long. And he still loves me! I am safe with him again."
Another said: "I am not sure if you still remember me. I'm the young man from Poland who wrote a message about how I was losing my faith. Now, I've almost finished Now a Christian and I feel thoroughly changed and challenged. It is a decision that changes a man's life."
Peter Graystone, one of the creators of Now a Christian, said: "I am surprised and delighted that so many people have used Now a Christian.
"Perhaps it has been so popular because it doesn't start from the point of view, 'We are Christians – what should we tell people?'
"Instead my starting point when writing it was, 'If I were making my first tentative steps toward faith, what would I want to know?' So it's simple, life-enhancing and utterly practical. And I hope it's enjoyable too."
