roles vs. gifts in Christianity

I find this snip from C. Peter Wagner on the roles of the Christian and their overlap with spiritual gifts interesting especially in light of conversations I have had with gay Christians who assert that gay marriage is acceptable to God since burning with lust is not, 1 Cor. 7:9.

Roles are Christian practices such as having faith or being a witness to the gospel. They are slightly different from the fruit of the Spirit in that they involve more doing than being. And they are different from spiritual gifts and similar to the fruit in that they a re expected of every Christian.

Faith is a spiritual gift and fruit of the Spirit that is also a role. Faith is required to become a Christian, but over and above this is the special gift of faith given by God to only a few members of the body. The gift of faith is much more than the fruit of faith and role of faith that we see in an ordinary Christian. Another example is celibacy. Some are gifted with it, but all Christians must be prepared to practice the role of celibacy if single or widowed or even when [apart from] a spouse. p. 189-190 The Portable Seminary, David Horton

I would also add chastity is also require for those who can't find a spouse in the faith (2 Cor. 6:14), or can't find a spouse at all, or can't find an opposite sex spouse (1 Cor. 6:9). The Bible is God's love letter to us. It's to our own pride that we should ignore it.
