I also think the world makes more sense if there is a God - but it seems I am not as certain about it as you are.
And yet when I asked you specifically about how the world makes more sense if there is a God, you said 'I don't know'. Apparently what you observe indicates that God should exist but doesn't tell you anything about what he might be like.
However I do not see how this is evidence for Christianity.
Because Christianity presents a picture of reality in which the problems of right and wrong that we face in every day life 'make sense'. I haven't found any other explanation that achieves the same.
How does it support the belief that Jesus is God's son and we are born into sin because of the sin of Adam, that we needed God to send his son to die on the cross to save us etc... To me the specific claims of Christianity make little or no sense and is one of the most compelling reasons to reject Christianity.
Because these are all element of that reality - each linked to the other - which, taken as a whole, 'make sense' of what I see around me and 'in' me.
You've mentioned this problem with being 'born into sin' before. For me that's one of the most obvious. That's what my conscience tells me all the time! I am in fact a git. And my 'gitiness' goes deep. Moreover, I see the same traits in pretty much everyone else I have ever met. Someone tells me 'well that's no surprise because that's the way all people have been since Adam' and suddenly it 'makes sense'. We are this mix of dignity and gitiness. So if someone else tells me 'there is no right and wrong except what you have made up in your own head' and my conscience is effectively lying to me by claiming that I have broken some kind of 'law' and the world makes signficantly less sense.
As for the "evidence" of the testimonies of people who witnessed him, I'm sorry but I have no way of knowing that these people even said what they are reported to have said - let alone whether they are telling the truth.
Ok. I don't agree that you have 'no way of knowing' but you asked for how I know. I can't speak for you.
