Are we afraid to die, that we're too much conscious of our food? lol
"That which enters into the mouth doesn't defile the man; but that which proceeds out of the mouth, this defiles the man." - Matthew 15:11
Mark 7:14-23: “Again Jesus called the crowd to him and said, ‘Listen to me, everyone, and understand this. Nothing outside a man can make him unclean by going into him. Rather, it is what comes out of a man that makes him unclean.’ After he had left the crowd and entered the house, his disciples asked him about this parable. ‘Are you so dull?’ he asked. ‘Don't you see that nothing that enters a man from the outside can make him unclean'? For it doesn't go into his heart but into his stomach, and then out of his body.’(In saying this, Jesus declared all foods "clean.") He went on: ‘What comes out of a man is what makes him unclean.' For from within, out of men's hearts, come evil thoughts, sexual immorality, theft, murder, adultery, greed, malice, deceit, lewdness, envy, slander, arrogance and folly. All these evils come from inside and make a man `unclean.’”
Deep down we humans continue to be beasts at least up to some degree. Many animals seek to survive at all costs, and in many cases, the big boss (stronger animal, etc) gets everything, including the female. We humans have a bigger brain, and all those primal instincts translate into more complex stuff such as "theft", "envy", etc, which are basically tools to bring us "to the top". Of course, many people are also downright psychopaths (murder just for fun, for example).
Jesus lived two thousand years ago, there's been enormous cultural and intellectual progress since then.
Some do not agree we have progressed as you claim. Intellectualism can be its own religion. Pride goeth before destruction.
how do you know he lived? how can you know, there wasn't some well paid writer, who wanted just to pay off his debt?
There's reasonable historical evidence for Jesus having lived. There's no evidence, however, for him having been a son of God etc.
I place my reasoning above not reasoning so in that sense I'm not a religious person but I know quite a lot about religion anyway. You seem to be choosing some verse that fits your belief.
