All of the years in Sarah’s life were equal in their perfection. Even though Sarah went through difficulties and struggles, she was continuously working towards excellence and reaching her fullest potential. Her actions gained merit for her generations after her.
Merit is timeless; it goes on forever. What we do today affects not only the present, but the past and future as well. Your life doesn’t end with you. Your children walk in and improve on what you’ve done.
When you are working on improving your life, it’s as if you are walking in perfection. As long as you are working towards excellence, your children are working towards excellence, because your matter is their matter, and your dust is their dust. No matter what you’ve done, and no matter what age you’re at when you begin to change what you’ve done—the moment you begin to make an effort to improve, God automatically straightens all of the previous years out and He makes for you a good name.
We think in “time”; God thinks in “timelessness.” We tend to look from the beginning to the end, but God looks at the end from the beginning. He has an advantage that we don’t have!
