What is the golden rule?
Jesus in his Sermon on the Mount [Matt 5-7] provided us with what has become or considered a 'rule of conduct' commonly called the Golden Rule. Jesus says: all things, therefore, that you want men to do to you,
you also must likewise do the them.
Living by that Golden Rule involves positive actions in doing good to and for others, treating them as you would like to be treated.
Jesus illustration of the 'Good Samaritan' is a good example of how to widen out in one's love for another.
Practicing the Golden Rule would not necessarily be easy because Jesus said to go in through the narrow gate because broad and spacious is the road leading off into destruction and many are the ones going in through it; whereas narrow is the gate and cramped the road leading off into life, and few are the ones finding it.
So being spiritually or religiously mislead is possible because Jesus went on to warn about false prophets or false clergy in sheep's clothing, but inside are ravenous wolves.
Good trees can be recognized by good fruit.
The bad fruits of false teachers and false religious leaders and followers can be recognized by bad conduct and bad teachings and actions not in harmony with Jesus teachings and example.
