"Let us consider the interesting but much-neglected question whether man stood in fellowship with the Holy Spirit before the fall." The truth is this: "The original Adam returns in the regenerated man.
"It follows that the Holy Spirit must have dwelt in Adam, as He now dwells in God's children…. [Yet] God's Word teaches the following differences between the two. 1. Adam's treasure was losable; but that of God's children, unlosable. 2. The former was to obtain eternal life, while the latter already possess it."
