The point of becoming a Christian isn’t to make your life better. Otherwise people would never become Christians in places like North Korea and Afghanistan, where they know they will encounter severe persecution, but they do.
For example, ‘if an Afghan's Christian faith is discovered, it can be a death sentence, or they can be detained and tortured into giving information about fellow believers… This means Christians – almost all of whom are converts from Islam – must keep their faith secret, or they may simply disappear.’ (Under Sharia law, leaving Islam results in the death penalty.)

J Warner Wallace, a former homicide detective, writes:
//At the age of thirty-five, it seemed like I had everything I could possibly want. I’d graduated at the top of my class… and was in an incredible job assignment… I had been with my wife for eighteen years and we had a great family. We just purchased our second home… Nothing could have been better. This was the status and condition of my life when I walked into a Christian church for the first time…
I’m not a Christian because it “works” for me. I had a life prior to Christianity that seemed to be working just fine, and my life as a Christian hasn’t always been easy.
I’m a Christian because it is true.//
