If you could do one on Baptism, that would be helpful. Can you go into more depth about physical and spiritual Baptism? And what Jesus means, I think in John 3 about it being water and spirit. Is the water spiritual, or is he referring to physical Baptism? Because the water bit has been used to argue for Baptism as a work for salvation and I don't have a solid answer to that. Also, can you talk more about Communion aswell, and how much do you think born again believers should put emphasis on partaking?
