Many Christians emphasize the importance of having an actual *relationship with God/Jesus* as opposed to merely being *religious*. The previously asked question https://christianity.stackexchange.com/q/69228/50422 attests very well to this fact.

How do Christians who subscribe to this distinction make sure that they themselves are having a **genuine** *relationship* with the living God, as opposed to a 'religious' illusion of it, a counterfeit relationship with a false deity, or a mere psychological delusion?
