Robin,

I think you are correct that one of the main reasons for discomfort is the knowledge that the gospel is offensive. There can be quite a fear of sharing the gospel for fear of losing a friend because they take offense or for fear of being ostracized for believing such "nonsense" or even for fear of losing one's job or other such things. Another factor I think is a fear of getting it wrong & misleading the person you are trying to proclaim the gospel to. As you say, however, we ought to understand that it doesn't really depend on us - we are to be faithful witnesses, but it is God who provides the increase.
