Saint Faustina wrote that the Lord said to her, “Even the devils glorify My justice but do not believe in My Goodness.” What is Creator’s perspective?

This was an inspired awareness coming via her higher self to help guide her to embrace her spiritual perspective along with a warning to be wary of the darkness as an enemy, a temptation, and a menace needing to be avoided. That is sound advice for everyone because the darkness is real, ever-present, and relentless in seeking to overcome and overpower everyone and everything. That is its goal, not only to be a wrench in the works but to destroy everything but the wrench itself so that evil will reign totally and completely with a destruction of everything else. That is the ongoing agenda always and why the problem of evil is such an important goal to focus on to provide a solution. That is your charter as human beings, why you were created, why you are here incarnated at the moment, it is your purpose to take on the darkness and win the day, not by fighting it and destroying it but by healing it so it is raised up and its energy will once again be focused on love instead of hatred, on helping instead of hindering, and on creating instead of destroying.
