Let's get them sinners and turn em' into Saints! - ???

So I'm in an Evangelism class right now... and it's bogus.

My professor has all the makings of an exciting teacher. He is from Africa, he is a pastor, and has had some crazy experiences... But this remains in the top 3 worst classes I have taken my entire life.

Our big assignment for the course was to go out and manufacture a relationship with a "sinner" to get them to turn to Christ and to record the process in a journal.

I can not explain to you how hollow and sleazy that feels... Christ calls us to love people. There is a lot involved with loving people (most of which I don't yet understand) and I am sure that building up faulty friendships with the intent of "exploiting" them and then moving on if the effort seems futile is not what Christ had in mind. I understand how necessary it is to share the 'good news', and I recognize that there is a definite sense of urgency involved, as we don't know what tomorrow holds for us. But I cannot get beyond the cheapness of a hollow relationship.

St. Francis of Assisi said, "Preach the Gospel at all times and when necessary use words."

I don't want to reduce sharing faith to just living your life or to give permission to be lazy evangelists, as this quote has been abused by so many, but I do think that inherent in loving people is the desire to share the 'good news' with them and to offer a helping hand as a true friend.

How do we get past the mentality of exploiting friendships, while still pursuing people who do not know the Lord?
How do we balance being lazy/timid proclaimers of our faith and trying to primarily show Christ through our day to day lives?
What part does Post-Modern Relativism play in this whole thing? I have been doing a lot of reading regarding 'emerging' generations and churches and am still trying to get a grasp on the level of pluralism and relativism that is inherent in Post-Modernity, but what approaches do we as Christians take in response to the troublesome aspects that come along with some of the freedoms and exciting parts of Post-Modernism?

And that's all I have to say about that...
