What beliefs would we consider reasonable for a self proclaimed Christian to hold?

Okay Mr. Smarty, show me where in scripture God says we have to prove His existence to anyone. Christians can't even prove it to themselves, God reveals His existence to us, like I said it is His work. Then deluded one is the one who answered my post and wrote the above rubbish.

Spreading the word of god:
https://www.openbible.info/topics/spreading_the_word

Christians are tasked with spreading the word for the purpose of saving souls.  If stands to reason that if the christian encounters a non-believer that the christian is tasked in ministering, proselytizing, in order to convince the non-believer of God's existence.

 Wrong, we are to witness to the people what God has done for us through Christ, it's the Holy Spirits job to convicted the people of their need for Christ and the peoples responsibility to accept Christ and by grace through God they will be saved. This is what we are to do and no where in that is it my responsibility to prove God and by the way you have neglected to show me where in the scriptures I'm required to prove God to you or anyone else.

You are incapable of seeing the truth of which I speak of. Only God can reveal it to you and He has called me to witness to you so that you might hear His truth. I've heard and seen His truth and it is the most remarkable thing one can possess. I can't lose my salvation because I've already answered the Holy Spirits calling, if you knew anything about Christianity you would know the difference. You sure are hung up on dreams aren't you, must be some kind of problem, hope you can get that fixed. I guess if you stay on the path you are now that some day you will realize the value of salvation and wish you had received it before your death. Jesus said, "what does it profit a person to gain the whole world and lose your soul. The world is temporary and the next life is eternal whether you be in heaven or hell.

So, only God can reveal his truth to us but declines to attend to this matter himself. Instead, he sends a proxy.

God has chosen to work through people, our work is to witness and then once a person accepts Christ, God will reveal the rest of His truth. Once we are saved we are not to set on our hands we are to go to work telling others of the Good News of Jesus Christ among the many other things we can do for others.

God chooses you, of all people, to help us see this truth. But you are singularly bad at persuading anyone of anything.

That's an opinion by you, who has glued blinders over your eyes. There are people out there that would whole disagree with your opinion because they found the truth through my life with God.  

Your utter failure as God's representative can't be your (or God's) fault, so we must be 'incapable' of seeing this truth of which you speak. For that, we are to be punished eternally. Now step back, GC, put down the Kool-Aid, and think. What part of this scenario strikes you as not monstrously fucked up? 

  That bold sentence (by me) makes no sense at all, how could I fail if it is you who can't see the truth and it's certainly not God's fault, you want listen to Him. So yeah the failure is your responsibility and if you knew the scriptures you would know this. When you come to understand God's plan you would know that the responsibility is yours alone to come to Christ as your savior and if you do not you are writing your own eternal punishment. You should stop writing and listen, it is more profitable.
