Youthwork innovator Mark Yaconelli was at Greenbelt this year with a range of talks on life, ministry and spirituality. We're releasing one of his talks – "The three desires: Christianity as a spiritual path" – for you to download free from this post, or via our podcast stream.

The titular three desires are, according to Mark, those "that burn within every human heart: to know a larger Source of love, to hold love for ourselves, and to share love with others". The talk explores Christianity's empowerment of the individual to follow "a life of contemplative communion, creative expression, and compassionate action".

Mark Yaconelli is an author, speaker and retreat leader, and the co-founder of Triptykos, a public action programme for engaged compassion at Claremont School of Theology in California, USA.

If this piques your interest, we have plenty of other talks by Mark from his appearances at the festival in 2008 and 2010, and don't forget that we have hundreds of talks to browse and download in our online Talks store.

To celebrate the launch of this year's lineup – you have bought your tickets haven't you? – here is one of our most popular talk from last year's Festival.

Rob Bell's conversation with Greenbelt trustee Martin Wroe is an insight into his life and work and his views on everything from animal noises to the afterlife.

Next Saturday tens of thousands of people will gather on the streets of London to make a final call for climate justice ahead of the UN Copenhagen summit. We hope to see you there.

To get you in the mood, this month's free talk comes from Tamsin Omond. In WWJD Tamsin asks how Jesus would respond to the current crisis:

"I don't know what Jesus would do with this world. I don't know how he would challenge the tangled webs of power that be. I don't know if he'd be vegie or vegan. If he wouldn't fly to the conferences to which he was invited. If his house would be an eco-haven. I don't know if he would go out and protest. I don't know how he would respond to the responsibility he shoulders. Would he be in the developing world, helping those on the front line of climate change? Or would he be obeying the law, having faith that somewhere out there our future must be in good hands? Or would he be a superhero of the environmental movement, exposing government wrongs there, shutting down carbon intensive infrastructure here? How would he transform hearts and minds? It's impossible to know.

Is it a paralysis or is it a call to action so compelling that it does transform lives? That you give up your ambitions for luxuries that you'd always imagined having and instead become one small part of a very small group always on the brink of being overwhelmed. A group of people that have faith, that believe we can transform this world, that humainty is worthwhile enough to dig itself out of this mess."
