Like so many common verbs, the meaning of "know" in the Bible is varied and dependent on context. And in some cases -- when it is connected to ideas or objects -- its spiritual meaning and natural meaning are essentially the same. When the Bible talks about people knowing each other and especially when it talks about the Lord knowing people, the meaning has more to do with the states of love within people than it does with any factual knowledge. This makes sense if you think about it. When we really "know" somebody, what we mean is that we know what kind of person they are, what their motivations are, what they love, what they hate, what makes them tick. Those things are far more important than knowing their parents' names, where they were born or what year they graduated from school. Most often then, especially applied to people, "knowing" has to do with the perceptions we have about other people's loves and the conjunction that can exist between those with similar loves, not just a collection of facts.

Time is an aspect of the physical world, but it is not an aspect of the spiritual world. The same is true of space: There is no space in heaven. This is hard for us to grasp or even visualize, because we live in physical bodies with physical senses that are filled with physical elements existing in time and space. Our minds are schooled and patterned in terms of time and space, and have no reference point to imagine a reality without them. Consider how you think for a second. In your mind you can immediately be in your past or in some speculative future; in your mind you can circle the globe seeing other lands and faraway friends, or even zoom instantly to the most distant stars. Such imaginings are insubstantial, of course, but if we could make them real we would be getting close to what spiritual reality is like. Indeed, the mind is like a spiritual organ, which may be why physicians and philosophers have had such a hard time juxtaposing its functions to those of the brain. What this means in the Bible is that descriptions of time -- hours, days, weeks, months, years and even simply the word "time" itself -- represent spiritual states, and the passing of time represents the change of spiritual states. Again, we can see this a little bit within our minds. If we imagine talking to one friend then talking to another, it feels like going from one place to another, even though we're not moving. The same is true if we picture a moment from childhood and then imagine something in the future; it feels like a movement through time even though it's instantaneous. Changing our state of mind feels like a physical change in space and time. The Bible simply reverses that, with marking points in space and time representing particular states of mind.
