On one hand the author acknowledges spiritual gifts, but then seems to dismiss them in favor of just volunteering to serve the church with what you're good at. In doing so the author does his best to avoid some uncomfortable Scriptures.
The author never does manage to actually explain what spiritual gifts are. So, we shall do the author's work for him. "Spiritual gifts" in the Greek is pneumatikos charisma, of the spiritual realm, and, empowerment. The two words appear together only once in the Greek text, in Romans 1:11:
I long to see you so that I may impart to you some spiritual gift to make you strong...
gift to you spiritual
but the connection between the two is clearly presented in Scripture. Every spiritual gift is a spiritual empowerment.
This is quite different than a natural skill or ability. While it is certainly true that a person's natural ability might give a hint of a spiritual gift, a spiritual gift is a notably a supernatural endowment.
It is clear that some of these spiritual endowments make the author uncomfortable, because they are unnecessarily supernatural. The reason is, the author is a cessationist who doesn't believe in prophecy, tongues, words of knowledge, healing, or miraculous powers. Yet all these are listed as gifts.
So rather than engage these uncomfortable things the author either doesn't mention them or glosses over them. Though he manages to quote a few Scriptures, he doesn't quote any part of the verses that mention spiritual gifts.
We must therefore regard this as Bad Bible Teaching.
