I see a couple misunderstandings on both sides here...
First thing:
Being a Christian means accepting Jesus as your Lord and your saviour...and trusting that He is the way to God...(the one and only God Jesus speaks of in the bible).
Unfortunately, and believe me I know this might sound harsh, there is no room for other Gods/other explanations of “how” and “why” with Christianity...that's exactly what being a Christian entails...and before I became a believer, I used to demand to know WHY, WHY, WHY it is these "closed-minded" Christians think that way.
Well...now I know why. Because believing there is only ONE way, IS the only way (to come to God and to salvation). It didn't make sense to me until...well...until it made sense to me. It's the only way that works...and it's the only way that was meant to work. We didn't choose it to be so cut and dry. Blame Him! As Christians, we can't say there are others ways...that's not how Christianity works.
And for some reason, it seems popular these days for people to think its SOOOO horrible for anyone to say there's only one truth. It's like..."Well, sorry. But the truth I believe in just so happens to be about believing in ONE truth...I didn't make it like that. But I believe in it...it makes sense to me...so don't start making me look like the bad guy because I'm not willing to be what you call 'open-minded,' and accept there's possibly other God's/explanations/whatever...I just don't. Can't help it."
And I hope non-Christians here appreciate where I'm coming from. Because at the end of the day, I have as much choice to what makes sense to me, as you do to what makes sense to you...don't say I'm being condescending because what makes sense to me just so happens to be about Jesus being the only way.
…does that make sense???
Second thing:
Evangelizing to people isn't something Christians should think they need or have to do...or that it's a requirement of being a Christian.
If anything it should be looked at as a privilege. If you are a Christian, and you believe that Christ died on the cross for the sins of man, and that we are now in the process of the world being redeemed...it’s gonna happen with or without us. That's why God sent His Son...to redeem the world through him. We're just meant to take part by being Christians (and that happens by allowing yourself to become more like Jesus).
We're NOT gonna do it by telling people "this is what will happen to you if you don't accept God NOW!!!"
Would you be drawn to something like that?...or to something like Jesus (who came as a humble, loving, serving example of how we should treat and respect each other). By simply being a Christian, and acting out you faith, you ARE evangelizing.
Question is…is your faith being acted out (meaning, are you becoming more like Jesus?)
