Help! Parable or Riddle needed (mercy, justice, love, truth)

Okay, my GLP friends.

I am so close to having a first draft finished on another metaphysical book for young people, but I am asking for ideas about a riddle that I need.

Premise: In order to get to the Key, the characters need to decipher a parable or a riddle that combines four things:

Justice, mercy, truth, and love

These can be color-coded: red, blue, gold and white(?)

Or jewel coded: ruby, sapphire, gold, and diamond

It can also be square, circle, rectangle, and triangle.
Any combination that they must solve that shows who they all relate to the truth.
But somehow the answer needs to show that they are all necessary to find the truth.

Any type of parable or riddle idea is so awesome.

The key will be in one of them or in the answer.

Thank you for any ideas at all!!!!!
