What does the great commission mean to you?

Somehow I don't know how to interpret this. I mean does this mean that we, as christians, have to talk about Jesus with everybody we know and also with strangers? There is this guy, Ray Comfort, who has his style of evangelizing which is showing the people with the 10 commandments that they are sinners and then he asks them if God would send them to heaven or hell according to their sins and then most of them say hell. He says this works with everybody even with atheists but the problem is even if you convince an atheist that he is guilty according to the 10 commandments this will not impress him at all cause he doesn't believe in God.
The question is do we as christians have to go to everybody we know and talk with them about Jesus? I don't know but I wouldn't even know what to say. I have tried this a few times on the internet and it never worked it always resulted in discussions about evolutions and such things and I am not good at this and these discussions are also exhausting and in most cases I'm confused afterwards. I tried to talk about God to my family members and it always resulted either in discussions or disagreement or arguing. I ask myself where is the sense of this? I am not good at evangelizing and it has never worked and I also don't feel comfortable talking to strangers about Jesus I wouldn't even know what to say. I know people which study with me and I have never talked to them about Jesus simply because I don't think they would be open. I think it would end in a discussion about evolution or the bible and they would come up with claims and most likely I wouldn't know all answers and then they would be even more convinced that the bible is a joke. I am not an apologist. I don't have all the answers. I would most likely not be able to win a debate and then they would be even more convinced that they are right and maybe my faith would even suffer from this. So why should I go out and talk to people and maybe even harm my own faith? Trying to talk about Jesus can be very frustrating when you see that the other one isn't interested.
My personal opinion about witnessing to people is that witnessing out of a feeling of having to do it because God wants it isn't very helpful. My opinion is that when you notice that there is a situation where you get to talk about God with somebody and where there is an opportunity to share something then it's okay because God created this situation but simply talking to people and trying to convince them doesn't make sense. Or am I wrong? What do you think? What if I die and God is angry because I didn't warn others and share my faith? Many christians use this firefighter analogy where a house is burning and a family is dying and a firefighter sits in the car and doesn't help and then they say this is the same as a christian who doesn't warn the people. I think this analogy is not good at all. I mean think about it. Do you really think it would help the people if I went to them and warned them of hell and tell them they have to repent or they will go to hell? Imagine me going from house to house and warning them about hell. They would think I'm a lunatic. This wouldn't help anyone. This would even strengthen them in their feeling that christians are nuts. Simply warning the people doesn't help them because they don't take it seriously. Imagine you're a non-christian and in the shopping mall there is somebody standing there and preaching about hell, wouldn't you think that this is a lunatic from some sect and laugh about it? I would. This is how people react to something like this. So I think that when you think that you have done a great job simply telling people that they go to hell if they don't repent then you're wrong. This doesn't really accomplish much. Or what do you think?
Somehow I feel like I'm forced to go out and talk to people even though I don't know what to say. How shall I know if it's from God or not? After listening to Ray Comfort I feel as if I have to witness to every person which I see on the street and I don't know if this is really from God or wether I'm simply being obsessed with this and afraid of not obeying God.
How do I know if God wants me to talk to somebody or not? Or does God want me to talk to everybody? Does God want me to go from house to house?
Does Jesus saying that we shall preach to every creature mean that we, as christians, do not need an extra command from God in order to witness to a certain person but that God has already told us to witness to everybody and this means we HAVE TO witness to everybody. No matter if it's a witch or an atheist or a muslim or a mormon and we have to witness to them and go to their hourses? Or would this be silly because you might also get yourself into danger?

 

Oh boy....
I know this stuff, gekko. This is what kind of causes my problems because Comfort is of the opinion that you have to preach to everyone. But I am not good at this. I'm not Ray Comfort. Ray Comfort can debate with atheists and it doesn't affect his faith but what if it affects my faith? Why should I expose myself to their arguments and risk my faith? What if I try to convert an atheist and he converts me? Then it was really worth it, right?
This is what I mean with danger. Why should I expose myself to things which might negatively affect my faith? This would be very unwise. I cannot even really describe why I believe. I cannot nail it down to a superb argument. There is no argument. I simply believe because I do and I don't know why. I'm simply thankful that I believe but I cannot tell anybody why. This means I'm not a good witness. I could only repeat some good arguments for the bible but as soon as the other person would come up with questions I most likely would not be able to answer them. Those things which convince me might not convince somebody else at all and I really don't want to argue with atheists and hear their arguments because this has a negative effect on me. I have noticed this in the past. When I for example thought that I had a totally strong argument for christianity and then I told it to somebody on the internet and this person wasn't impressed at all then I asked myself what if this argument isn't that good and I only think it's good?
When you debate with an atheist and none of your arguments affects him then this will make you doubt your arguments and then you might ask yourself wether you're even objective and wether you not simply believe because you want to believe.

As for the firefighter analogy...
These christians make it look like those which do not warn everybody are watching them go to hell and don't care enough to warn them but this is not true. The thing is that I don't really expect my warning to accomplish anything. If I knew that warning the person would make her convert then it would be a totally different thing but most likely it won't do anything.But do you really think that a real atheist will be impressed when you tell him about hell? Of course not, he will laugh in your face. Or what about a self-righteous person? Do you think she will become scared? No. If somebody thinks he's a good person then he'll also not be scared of God. I have made these experiences. Simply going around warning people of hell doesn't save them, most of them will only laugh about it.
