The out of context gospel leads to all kinds of wrong thinking. I love Luke as a historian, but he wasn't at the Sermon on the Mount, while Matthew was. Before you invoke the Golden Rule, it pays to read it in context, because it wasn't spoken in isolation.

"If you, being evil, know how to give good gifts to your children, how much more will your Father in heaven give good gifts to those who ask Him?

In everything, treat others as you would want them to treat you, for this fulfills the law and the prophets.

Enter through the narrow gate, because the gate is wide and the way is spacious that leads to destruction, and there are many who enter through it. But the gate is narrow and the way difficult that leads to life, and there are few who find it. Watch for false prophets, who come to you in sheep's clothing, but inwardly are voracious wolves." Matthew 7:11-15.
