Puzzled about How Spiritual Gifts Work?

1 Corinthians 13

1 If I speak in the tongues of men or of angels, but do not have love, I am only a resounding gong or a clanging cymbal. 

2 If I have the gift of prophecy and can fathom all mysteries and all knowledge, and if I have a faith that can move mountains, but do not have love, I am nothing.

3 If I give all I possess to the poor and give over my body to hardship that I may boast, but do not have love, I gain nothing.
