I witness to a lot of young men usually in their twenties. When I witness I will get to know them first which may take a hour or two or a few days. I have noticed a trend by the majority of those I witness to. They have very fowl language, tell crude jokes about sex mostly, and the are very fond of drinking and partying. After I have gathered this much about them I ask them about their spiritual life and to my astonishment the majority of those who have these vices claim to be Christians and many within the SBC. Once they find out I'm a Christian I see no change in their language or crude jokes unless I ask them not to. I have two questions concerning this: Should I challenge their salvation with scripture or remain nutral about their vices? Secondly, does anyone else experience this?
