“O righteous Father, although the world has not known You, yet I have known You; and these have known that You sent Me.” (John 17:25)
Jesus makes it clear in this verse that those who are not His disciples in the world do NOT know God the Father, the One to whom He is praying here. He clearly says: “The world has not known You.”
— Significantly, He does NOT say that they just know Him by some other name; Jesus says they have not known Him.
— He does not say that God is so immense and incomprehensible that these members of other religions are just familiar with “another side of the elephant” that His followers aren’t touching. No, He says they have not known Him.
Do not surrender the vital ground of Jesus’ exclusivity to the assertions of worldly philosophers that “all roads lead to the same place” in religion, and that all religions equally know God, just a different aspect of Him, or just by another name. Jesus and His disciples make it clear in several places in scripture (John 14:6, Acts 4:12, I John 5:12, etc.) And He makes it very clear here as well: “The world has not known You.”
