Also I personally know people whose lives have been completely changed after believing in Jesus. For example my uncle who used to be part of Hell's Angels. One day he decided to believe in Jesus, and now he runs a drug rehab, is a deacon at his church, and runs missionary trips to preach the Gospel to drug lords in Columbia. Or take my own parents, normal college kids from middle upper class non believing households. My dad chose to follow Jesus while in the Navy, and then he and my mom devoted the rest of their lives to missionary work. Or my wife's mother who grew up living with people doing drugs and living promiscuously, and generally not going anywhere. She and her siblings chose to follow Jesus, left their situation, founded a church, all attended college and some gained advanced degrees and PhDs, and my mother-in-law ran a lab at John Hopkins. My perception is Christianity can certainly change lives for the better, in dramatic ways.
