Or do you think Scripture says without reason that the spirit he caused to live in us envies intensely?Unlike chapter 3 of James, which talks about human jealousy, this is divine jealousy.
The Spirit, rightly so, and rightly for our own good, is jealous over us. To be a person of one heart and one mind with the Spirit is what the Spirit desires. The best thing for us would be that sort of devotion.
I long for that with my own wife, not simply because I don't want to share her, but also because I truly believe in marriage! A devoted marriage is better and more fulfilling than any extramarital affair could ever be. So I envy intensely for my wife for both of our goods. The same is true of the Spirit.
