The Golden Rule is the principle of treating others as you want to be treated, that is found in most religions and cultures.
In the positive form, it is "Treat others as you would like others to treat you". In its negative or prohibitive form, it is "Do not treat others in ways that you would not like to be treated".
That Golden Rule makes logical sense, but it meets a contradiction when evil is returned for good.
We see this in the reality of life when good and innocent people suffer oppression and injustice from bad and evil people.
We see this in the 1st reading when the enemies of the prophet Jeremiah conspired against him despite the fact that he was just speaking the Word of God for their good.
Jeremiah cried out to the Lord and he also asked why evil is returned for good.
In the gospel, Jesus told His disciples that He would be handed over to the chief priests and scribes and that He will be handed over to be mocked, scourged and crucified.
But they didn't seem to understand that and instead they were thinking about what they can gain and how to rise to prestige and status.
Jesus then gave them a lesson on service and humility.
If we wish to serve as Jesus did, then we just have to keep focused and follow Him despite the bad and evil that we face in this world.
Let us be humble and keep doing good and to leave the bad and evil in the hands of God.
