The Holy Spirit does not just give believers a gift, the Holy Spirit IS the gift.
Don't be paralyzed with inaction trying to identify your "best" spiritual gift. Instead, focus on the ultimate gift, your relationship with God through the Holy Spirit. He gave us this gift so that we could always find it easy to be close to Him and serve Him.
But the Counselor, the Holy Spirit, whom the Father will send in my name, will teach you all things and will remind you of everything I have said to you.
