Welcome!
Spiritual gifts are merely appropriating the authority Christ holds in heaven into the world today. For example, God didn't intend us to be sick. satan afflicts us with sicknes because of the authority he has over us (thank you Adam ; ) A gift of healing is the authority of Christ working to thwart the authority of satan.
That's a distilled, Readers Digest version but I hope you get the idea.
And be aware there is a lot of contention regarding the subject. Don't be dismayed if the road gets a little rough!
