Path of Truth & Error Lie Close Together

Since the begining, the path of truth & error have lain close together. In the garden of Eden, the tree of the knowledge of good & evil was just that-of good & evil. Not the tree of the knowledge of good. Not the tree of the knowledge of evil.
"The track of truth lies close beside the track of error, and both tracks may seem to be one to minds which are not worked by the Holy Spirit." Selected Messages vol. 1, p202 E.G.W.
....the tree of life also in the midst of the garden, and the tree of knowledge of good and evil. Genesis 2:9
