N.T. Wright offers a detailed account of how Christians should practice virtue. Virtue does not come spontaneously and it may not feel sincere immediately, but believers need to practice patience, hope, mercy, love, etc...nonetheless, just as a piano player does not become a virtuoso overnight.

Personally, I don't find I learned a whole lot from this book. I already agreed with Wright's assertions about the need to practice virtue. He could have written more succinctly. Also, many of Wright's "popular" books pick up on themes already found in C.S. Lewis' work. If "Simply Christian" was made to be a 21st-century update of "Mere Christianity" then "After You Believe" could be the "Christian Behaviour" section that comprises the third part of "Mere Christianity."
