Final Exams

This week at the university, I am giving final exams to my students. I can't help but think that God is happy when His students (us) pass the exam. Unlike my Spanish students, God's exam is Pass/Fail. He either tells us "Well done!" and shows us into heaven, or He says "I never knew you" and failure has an eternal price. It was fun to grade the exams when the student had grasped the material and I could see that learning had definitely taken place during the semester. It was disheartening when the pages bled showing that the opposite was true. Does God ever shake His head at us wondering when we will finally get it?
