At the very beginning of the fourth chapter of Engaging God's World Cornelius Plantinga defines grace as mercy to undeserving. By this definition we all receive God's grace, because none of us deserve to go to heaven. Sometimes people get caught up in saying that it's not fair that some people have to go to hell, but it is quite the reverse. None of us deserve to go to heaven, because we have all sinned, but through God's grace we are given the opportunity to go to heaven.
Recieving this grace might sound fairly simple, but it is a constant battle. God has given us a guide to follow though. Plantinga claims that the Ten Commandments are a recipe for freedom. Even though we have ten absolute laws our lives and the Church can always be improved. We do not need to change the Ten Commandment; we need to change the way we live our lives. There is always room for improvement.
Plantinga points out that we all need a miracle. None of us can do this on our own; none of us can redeem ourselves or lead perfectly Christian lives. It is through the saving grace of Jesus Christ that we are all saved.
