Even when you are old, I will be the same. Even when your hair has turned gray, I will take care of you. Isa 46:4
Growing old can be dangerous. The trail is treacherous and the pitfalls are many. One is wise to be prepared. You know it's coming. It's not like God kept the process a secret. It's not like you are blazing a trail as you grow older. It's not as if no one has ever done it before. Look around you. You have ample opportunity to prepare and ample case studies to consider. If growing old catches you by surprise, don't blame God. He gave you plenty of warning. He also gave you plenty of advice.
Your last chapters can be your best. Your final song can be your greatest. It could be that all of your life has prepared you for a grand exit. God's oldest have always been among his choicest.
