As many have pointed out The qualifications of being a "spiritual man" in JW legaleas means how how high they can jump based on works supporting the publishing company WTB&TS.
The scriptures point out that being a spiritual person is all in the mind, or the point of view. The fruits of the spirit, love, joy, peace etc are the qualities displayed by a spiritual man. WT has perverted this higher mind and thinking level to mean regular meeting attendance, field service hours, commenting at the WT word for word, and complete submission to the indoctrination by the WT.

Year's ago, WT waffles on the being appointed by spirit meant that if everything turns out in his life ok, then the individual was finally appointed by spirit. If he turned out to be wicked, he was never spirit appointed.
Jesus prayed over the appointment of the twelve and still had Judas betray him. Oh, but that was prophesized.
