That is the point here. Not "who we know" but WHO we know, "in Spirit and in Truth".
If we say - we can't know the Truth - we make GOD to be a liar.
If I were to use the "who I know" way of posting - I would say, I know that MOST Christians don't Study His Word as they should and use the "we can't know it all" excuse - that is not found in His Words - and as a cover for the fact that we've wasted our time with "other things" besides, "seeking out His Truth" - which is synonymous with "seeking Him" WHO IS The Truth. GOD forgive us.
