LIFE IS A DIVINE CLASSROOM FULL OF TESTS
If we take the mindset that our time on earth is that of a classroom or school, we would understand and accept that every storm, trial, challenge, and difficulty was a test. Tests are given by teachers to check for student understanding and to see whether they have mastered a skill.
Teachers introduce a concept and model it. The life of Jesus on earth, His death, and resurrection takes care of this step (Basically the Gospels of Matthew, Mark, Luke, and John).
