A note from Joyce
No matter how young you are right now, I think it is important to think about your latter years. Let me encourage you to look forward to them and believe that even though life will be different when you are older, it can still be very, very good. I don't want to expect my body and mind to break down at a certain age because that's what the experts predict. I want to see what God does with me. I believe that He has an individual plan for each of us and for the course of our lives. If we follow His guidance, we will end up at the right place at the right time.
Before you read further, let me challenge you to ask yourself an important question: Will you simply let yourself 'get old,' or will you age gracefully, purposefully, and wisely, allowing God to use you in every season of your life? If you will, I believe your latter years can be absolutely wonderful."
