The spirit of man introduced in any of these cases would not only weaken and destroy the truth intended, but render the reasoning null and void; and so it is down to ver. 16, where first we hear of “our spirit,” and here only. For in vers. 23, 26, 27, it is beyond doubt the Holy Spirit. It is true that ver. 10 implies that we are quickened inwardly, but the inspired word goes further.
