The church of England challenges its members to "adopt as an initial target the giving of 5% of their after tax income to and through the church, and a similar amount to other work that helps to build God’s kingdom". 
Should the church also encourage people to make these donations to impactful charities in order to use their talent well, given that there are great differences between the impact of different charities?

Maybe asks how he chooses which issues to focus on?

The story of Jesus being anointed by a woman with a costly jar of perfume leads us to the question of how we should divide our resources between religious gestures (“praise”, if you like) and helping the poor.

What does he think about AI risk and what does he think humanity should do about it?
