My son’s blue eyes sparkled with excitement as he showed me a paper he had brought home from school. It was a math test, marked with a red star and a grade of 100 percent. As we looked at the exam, he said he had three questions left to answer when the teacher said time was up. Puzzled, I asked how he could have received a perfect score. He replied, “My teacher gave me grace. She let me finish the test although I had run out of time.” As my son and I discussed the meaning of grace, I pointed out that God has given us more than we deserve through Christ.
