The Creator Creature gap is bridged by natural and special revelation. God in his otherness communicates through condescension in the form of covenant. Believer and nonbeliever can communicate by means of human language. :smug_b: No seriously. There isn't any nuetrality because the unregenerate's word-view is constantly skewed by their suppression of God's truth. Christian theism is antithetical to the unregenerate. There is no common ground that they can go to so that truth can be made available to the needy unregenerate. Though they may agree on certain things the unregenerate will always be inconsistent or even simply offer naked refusal rather then accept God's truth. Their wicked heart does not give them ability to bow to God's gospel command, even if every evidence is piled upon their stubborn necks. They are from the get go hostile to God's law and gospel.
