How Do You Know They Are Christian?

In my experience in Christ-centered counseling, nearly 95% of the people who claim to be a Christian cannot articulate or answer simple questions correctly about how they know they are saved. Even when ruling out the fact that some may have difficulty discussing such a deep probing question, it becomes evident that nearly all of these people are not saved based on their own words. Likewise, after a few sessions it becomes clear that the same holds true for evidence of their salvation based on their behaviors. This leads one to wonder how do you know they are Christians? God’s Word has the answer.
