What are Christian guidelines for making the transition from "knowing about God" to "knowing God"?

My question is motivated by Eleonore Stump's video [Can Philosophy of Religion Find God?](https://www.youtube.com/watch?v=l4Qa1gAj7zY) , suggested by this [answer](https://christianity.stackexchange.com/a/100465/61679) . In the video, Stump elaborates on how philosophy of religion can be helpful in understanding facts about God, likening it to acquiring biographical information about a third person, from a rather distant perspective. This stands in sharp contrast with someone who possesses direct, intimate, one-on-one experiential knowledge of a person. [Some would even argue that God's existence can be established rationally using reason alone](https://christianity.stackexchange.com/q/100436/61679) , which is a point of contention, but even if we concede it, knowing that God exists intellectually is unlikely to be the same as knowing God personally. What are Christian guidelines for making the transition from "knowing about God" to "knowing God"? --- **Note**: Having an intimate experiential knowledge of God resonates strongly with *Christian mysticism*, by my lights (see [here](https://christianity.stackexchange.com/q/98050/61679) and [here](https://christianity.stackexchange.com/q/98040/61679)) . However, I acknowledge my potential bias in this matter and remain receptive to insights from various Christian traditions, which might suggest different approaches to knowing God personally. Considering this, perhaps transforming this question into an overview of different viewpoints would be beneficial?
