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. We deserve death because of our sin (Rom. 3:23). Yet, “while we were still sinners, Christ died for us” (5:8). We were unworthy, yet Jesus—sinless and holy—gave up His life so we could escape the penalty for our sin and one day live forever in heaven.
Eternal life is a gift from God. It’s not something we earn by working for it. We are saved by God’s grace, through faith in Christ (Eph. 2:8–9).
