My view is that you shouldn't socially punish people for their sins - it is not our place to act as judges on non-Christians, not yet at any rate.
It's one thing to acknowledge that we are all sinners, that we all need salvation and forgiveness, and to lovingly present the gospel - it is another to attack people for their sins, verbally or otherwise.
Homosexuals are a great example of a group of people that the modern church tends to outcast and condemn.
That would depend upon the manner in which you presented the gospel. If your going around yelling at people that they are going to hell - then yes it would be wrong.
Yes, that would be really bad. It's not effective in the least and only makes a mockery of Christianity.
You said "This is exactly what Jesus did" in response to my condemnation of the preachers on campus - no Jesus did not act like the preachers on campus. If you saw them - you would be (or should be) appalled. The example was not simply going to college and telling people about Jesus (that is fine and good), the example was in reference to the campus preachers I'VE seen.
Also, while repentance was definately big in Jesus' message, he was not going around attacking people for their sins - that is what campus preachers do. They don't spend time to get to know people, they don't meet their needs - they simply show up and start condemning them - that is NOT Jesus' model.
Dude, you are so frustrating.
I give you an example of a method of evangelism (go to a college, tell people to repent and trust Jesus, if they reject tell them they are going to hell and judgment day will be really bad for them). Then you say, that's the wrong way to do it. Then I show scripture that shows my example is exactly what Jesus did.
Now you are telling me that you weren't disagreeing with my example, you were disagreeing with the example of some campus preachers that I've never seen and know nothing about.
How are we supposed to have a conversation when you are seemingly responding to my example yet secretly disagreeing with the example of someone else?
