The ComRes survey of 2000 eleven to 18 year olds in England also found that despite this, 56 per cent of non-Christian teenagers said they'd be comfortable with a friend talking to them about faith.
Jimmy Dale who is the Church of England's Youth Evangelism Officer told Premier's News Hour the research leaves a big challenge.
He said: "How do we help young people to see that actually firstly that they have something which is worth sharing but then secondly, what they are wanting to share, people are actually willing to listen to?
The research revealed only half of the young people believed Jesus was a real person with even less saying Jesus was a real person but not God.
More than half of the youngsters said they knew someone that followed Jesus with 67 per cent describing their relationship with Christians as friendly. Just 33 per cent of the same group described the relationship as fun.
One in four young people admitted to being afraid of causing offence when evangelising, which Dale said could be reduced if "we raise confidence" in them to share their faith.
