The problem with gifts and talents is that they can go to our heads. We can consider ourselves more important than others. We can consider our gifts as more important than other peope's gifts.
That's why Scripture says gifts are not enough. Without one ingredient, any gift, all gifts are vain, fruitless, death giving and glory robbing.
Love needs to power all gifts. Love needs to power how we express our gifts, look at others' gifts and receive grace/gifting from other people.
Love will outlive all gifts, all "spiritual manifestations", all theories and all ministries. What will last of individual lives is how much love did they give.
If love powers spiritual gifts, a spiritual gift is God's special of expressing love through each person.
