Grace alone means just that. Grace alone. (void of any works)
We can either earn what we have, and thus it is a reward or wage (works) or we are given what we have as a gift, because we can not earn it (grace)
I think i disagree with this EG. If one has Holy Spirit, we are given gifts. The work through these giftings are of the Lord, and are for the good of others. Like this thread. It's a work of God, yet it was started by Dcon. Am not even speaking of tongues here.
We flow in union with Him, so there can't be no works.
In my mind it is still grace alone. We wouldn't have giftings if not given to us. We are empowered.
Or understanding truth even. We see in scripture where the mind is opened to the truth by Holy Spirit too.
Praying for each each other then becomes really important. Probably the work assigned but we skip over it.
