The seemingly new abilities that may be gathered on the way can be very helpful.

Given to the Holy Spirit, and used under His direction, they are valuable teaching aids.

To this, the question of how they arise is irrelevant.

The only important consideration is how they are used.

Taking them as ends in themselves, no matter how this is done, will delay progress.

Nor does their value lie in proving anything;

God gives no special favors, and no one has any powers that are not available to everyone.

Only by tricks of magic are special powers "demonstrated."
