When this question is presented, I quickly go to 1 Corinthians 13:9. I really like the way the Amplified Bible translation puts it, saying: “For we know in
part, and we prophesy in part [for our knowledge is fragmentary and incomplete]". The reason I go to this scripture is to first establish that Paul is writing "we know in part". Our
knowledge is incomplete, but that does not mean we are not aware of particular things. Our knowledge is fragmentary, meaning broken or small. Our minds cannot understand the total power of God,
however, there are things we do know.
