The second part of 1 Corinthians 8 says, the same Spirit gives another the ability to speak with knowledge. Knowledge and wisdom are listed as two separate gifts. The Bible doesn't give us a clear definition of the gift of knowledge but I will attempt to make sense of it.
HELPS—Word Studies defines the original Greek word as 'functional ("working") knowledge gleaned from first-hand (personal) experience.' It's a bit like saying, 'I know about gravity because I fell out of a tree when I was six.' I know about it because I experienced it. I think that it's similar to someone having the gift of knowledge—they know because they have experienced it. Many people know that God loves them, but it's just a head knowledge. Other people have experienced his love in a powerful way and it has moved from being a head knowledge to a heart knowledge. The Holy Spirit gives us this knowledge, you can't learn it.
Here's another illustration. If you haven't seen snow you can still know about it—you know that it's white and cold, you could even imagine what it feels like. But if you have stood in the snow, touched and tasted it, you know about snow on a whole other level.
In my understanding, the gift of knowledge is linked to our experiences as the Holy Spirit helps us to understand them. It gives us a new perspective. Some people have the gift of seeing things from a God point of view, instead of a human point of view—I think that is part of the gift of knowledge. Hope that makes sense.
