He got it wrong.<quoted text>When asked about the Ten Commandments, Jesus replied to it.
35 Then one of them, which was a lawyer, asked him a question, tempting him, and saying,
36 Master, which is the great commandment in the law?
37 Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind.
38 This is the first and great commandment.
39 And the second is like unto it, Thou shalt love thy neighbour as thyself.
40 On these two commandments hang all the law and the prophets.
The second should be the greatest.
Why? Because it's a variation of the Golden Rule - I guess you've heard of it.
The Golden Rule is all about ethical goodness on a reciprocal basis and you'll see it manifested in numerous religions in many different words. As you stated, Jesus mentions it in the NT although he was far from being the first.
I'm sure you'll agree that wishing no harm or suffering on others is understandably a good thing. Yet harm is exactly what your god wishes on people and he expects his followers to obey him and break the Golden Rule.
Surely the merit of any religion isn't what you believe in but more about what you do? In other words, it's all about how you treat your fellow human beings. Extending the same treatment to other people that you would expect them to extend to you is undoubtedly the pinnacle of human ethical behaviour.
Also, if God/Allah/Brahma/Shiva/etc, really do exist, yet they insist that we humans must break the Golden Rule to get to Heaven; then they aren't worth thinking about.
Let's look at the god of the Bible: His main condition for us to get our pass for Heaven is not about treating our fellow humans decently and respectfully. Oh no, the Golden Rule doesn't matter to God. All that matters to him is that we love Jesus more than anyone else and with every fibre of our being.
You may like the idea of spending eternity with such a vain, egotistical, self-centred deity but not me.
