How do Christians who emphasize the "religion vs. relationship" dichotomy respond to claims of "relationship with God" in other religions?

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. But what about when people from other religions claim to have similar personal relationship experiences with their deities? For example, a Muslim claiming to have a personal relationship with Allah, a Hindu claiming to have a personal relationship with Brahman, a Hare Krishna claiming to have a personal relationship with Lord Krishna, a New Ager claiming to have a personal relationship with the Universe, their spirit guides, their higher self, etc. Qualitatively speaking, what sets the Christian *relationship with God* apart from *relationship* experiences that people claim to have in other religions? What makes the Christian *relationship with God* special and unique? Are people in other religions just having counterfeit, deceitful experiences? ____ Related: - https://christianity.stackexchange.com/q/84362/50422 - https://christianity.stackexchange.com/q/86124/50422
