Answer:
In simple words, failing god refers to the destruction of inner satisfaction that we get by doing something unethical. God wanted this world to be a happy place filled with kindness and compassion and every time we do something immoral we fail god severely.
As a result, God's kindness, kindness, and atonement cover our sin. His compassion gives us permission to do whatever is right rather than what we want. If you fail a religious test, it merely means you'll have to take it again. Which is excellent since a redo gives you another chance to absorb the material and take the exams.
