I think it would be fair to say also from this text that you shouldn't bend your mind too much trying to label your spiritual gift before you use it. Then do or say what seems most helpful and if the person is helped then you may have discovered one of your gifts. We must not get hung up on naming our gifts. I really believe that the problem of not knowing our spiritual gifts is not a basic problem. More basic is the problem of not desiring very much to strengthen other people's faith.
Human nature is more prone to tear down than it is to build up.
The path of least resistance leads to grumbling and criticism and gossip, and many there be that follow it. But the gate is narrow and the way is strewn with obstacles which leads to edification and the strengthening of faith. Grant that at the end of this day somebody will be more confident of Your promises and more joyful in Your grace because I crossed his path. The reason I say becoming this kind of person is more basic than finding out your spiritual gift, is that when you become this kind of person the Holy Spirit will not let your longings go to waste. He will help you find ways to strengthen the faith of others and that will be the discovery of your gifts.
