Question: How can you tell if someone is truly a Christian or not?  Are there things that demonstrate a person’s spiritual condition?  Also, if you see someone living a very immoral lifestyle, contrary to the Scriptures, is it wrong to assume they are not a Christian?  Or is that just judging?

My Answer: Good questions.  In a culture that is infatuated with “tolerance” and acceptance of every lifestyle and belief system, it seems harsh to state that any certain person is not a Christian.  Indeed, if you say that about someone, you very likely will be accused of being judgmental and mean-spirited.  As always, the Bible itself provides the best answers.
