Why Christians insist they are right?

Agree, we have never met God neither see Him face to face.
But, don't you think it is a little arrogant to ask Him, such honorable, majestic being to prove it to you? Who are you to deserve such answer? Are you holy enough to be able to face Him?

Yes, there are many religions out there but they are all contradictory to one another. The only common thing between them is that:

• they all recognize there is good and bad
• we are not perfect/sinful
• the way to perfection/salvation for ourselves and surrounding
  
• life after death (whether exist or not)

But, the fact that all religions have different beliefs or even contradictory, to say both are correct is nonsensical. Since all religions differ on the points above, our effort to find the truth is made easier. We are given intelligence to decide, to sort these beliefs and we will come to one.
Many people are not opened to this simply because they are afraid. They are too comfortable with what they believe in and can not be bothered. Because if they found out they are in the wrong side, they will panic.

Of course I think my belief is right. At this moment, we disagree with each other yet each one of us insist that each belief is true. You believe that there are more ways to go to heaven. You absolutely believe that God exists but the way to Him is unknown and you absolutely do not trust religion. Because you absolutely believe that religion is man-made. At this stage, I can only say that there are only two possibilities:

1. Either I am right or you are right
2. Neither of us are right

The fact that we are contradicting each other, both of us simply can not be true.
