Our reasons for believing Jesus existed and also that He was who He claimed to be - the God who came down - are the same reasons for believing any fact of history: the documentation is substantial and it passes all the tests of historical reliability. Scholars - both liberal and conservative - overwhelming agree that Jesus of Nazareth was a man of history and the Gospels, on the main, tell His story accurately.
Greg KouklIn the Story of Reality a man is a helpless slave - enslaved to his own passions, the flesh, and enslaved to a cruel master, the devil - a slave who God Himself rescues and adopts into His own family. It is the very worst news coupled with the very best news.
Greg KouklOur innate, built-in human value is the reason we have binding duties or obligations towards each other that we don't have towards any other kind of thing. It's also the reason we have unalienable human rights. If man's God-given, special value falls, then unalienable human rights fall, too.
Greg KouklEvery worldview has its ambiguities - debatable elements that people simply will not see to eye on. There's nothing wrong with that as long as the disagreement is principled and dignified. I actually think that arguments - as opposed to quarrels - are good things because they're the best way to figure out what's true. Share your reasons, listen carefully to each other, be nice, and may the best idea win.
