Firstly, thank you for taking the time to be so thorough in your response.The existence of God and the character of God are two separate issues, and really should not be linked when discussing the existence of God. Just because one finds God to be malevolent, or if one is angry at God (which suggests a belief in God), does not mean God is nonexistent. Similarly if someone finds that God is detached/not involved does not necessarily mean that God is nonexistent.
Christians believe that God exists. Jesus is the best evidence. The evidence includes, 1) his resurrection on the third day, 2) his transfiguration, where he appeared next to Moses and Elijah, witnessed by disciples, 3) his miracles, 4) fulfilled prophecies of the Old Testament, and so forth. The Gospels were written based on personal experiences which Christians consider as reliable biographies of Jesus. (For some, that fact that the Gospels were written based on personal experiences, rather than dictated by God, may be a plus.) One example, the introduction to the Gospel according to Luke states, "1Many have undertaken to draw up an account of the things that have been fulfilled[a] among us, 2 just as they were handed down to us by those who from the first were eyewitnesses and servants of the word. 3 With this in mind, since I myself have carefully investigated everything from the beginning, I too decided to write an orderly account for you, most excellent Theophilus, 4 so that you may know the certainty of the things you have been taught." Here, the author is stating that there were many eyewitnesses and that he too "carefully investigated everything" so he can write an orderly account. The author was an investigator/researcher. By addressing to "most excellent Theophilus," it appears that the author is being paid to investigate or is investigating for a prominent individual/benefactor. Paul's letters are also remarkable knowing that he transformed from a violent/murderous zealous anti-Christian Pharisee to the greatest evangelist (huh?), thus speaking to the power of Jesus. For these reasons, and there are more, Christians take the information about Jesus as reliable.
Next, on the characteristics of God, no doubt there are some difficult passages in the Bible. I do not think we can fully understand the nature of God. How can God be all-loving and just (showing judgement/wrath) at the same time? An all-loving God is not just; a just God is not all-loving. However, God is both. One thing is clear - God demands our loyalty and obedience, however he will pursue us (Parable of the Lost Sheep) and is all-loving and forgiving. On God asking Abraham to sacrifice Isaac, God was testing Abraham's faith (he actually did not want the sacrifice). God even wanted to kill Moses for breaking the covenant of circumcision. Gabriel the angel made John the Baptist's father temporarily mute for presumably unbelief. God's character is both love and judgement/wrath; that's the reality.
We, and unfortunately also children, are not spared from suffering (primarily caused by "sin"/ wickedness and state of the world). Here is what Paul said of his sufferings: "I have worked much harder, been in prison more frequently, been flogged more severely, and been exposed to death again and again. 24Five times I received from the Jews the forty lashes minus one. 25Three times I was beaten with rods, once I was pelted with stones, three times I was shipwrecked, I spent a night and a day in the open sea, 26I have been constantly on the move. I have been in danger from rivers, in danger from bandits, in danger from my fellow Jews, in danger from Gentiles; in danger in the city, in danger in the country, in danger at sea; and in danger from false believers. 27I have labored and toiled and have often gone without sleep; I have known hunger and thirst and have often gone without food; I have been cold and naked. 28Besides everything else, I face daily the pressure of my concern for all the churches." God allows suffering for His glory, and we do not always know why we must suffer sometimes.
In sum, for Christians, the evidence for God is clear. On characteristics, no one can ever stop learning about God.
I am a sceptic - believing that only the limited resources of my own mind can help me to navigate a way though this maze of life.
It is also crucial to me that my mind is not contaminated by the fear that the bible insists on propagating throughout both it's testaments.
To me, the concept of original sin is both ridiculous and vile - and there to make grovelling terrorised sinners of us all.
I don't buy it - but then I am a failure of religious indoctrination.
Making sense of anything means questioning everything.
As to the eye witness accounts of the gospellers,
scholars believe that the gospels were written between 66 AD and 110 AD, and could not therefore have been written by the witnesses themselves, who would most likely have been dead by then
Therefore, the history of Jesus must have been an oral history only until that time.
One thing is certain - they were not written by men named Matthew Mark Luke and John.
Hardly Hebrew names.
The bible has been written, re-written, edited, re-edited countless times, and as such is a doctored tome whoever you choose to look at it.
I would be interested to know of your own religious history - your early influences - do you regard your early religious education as an attempt at indoctrination.
My indoctrination lasted from birth to age 18.
Thank you again for your time and scholarly appraisal.
Despite my own views - I do appreciate it.
