People become enlightened and wise or bitter and more stubborn than ever as they grow old. Let's look at the latter case first. The worst example would be someone who complains about everything and blames others always and never himself. He's set in his ways because he believes that's how God has made him. Of course, I am describing an extreme case, but I've known people more or less like that. On the other hand, he one who grows wiser realizes that he must depend upon God more as he grows older and weaker. This is a true blessing as he finally sees the reality. Now, abandoning yourself to God doesn't mean that you no longer ask God for favors. In fact, you are now free to ask for all the blessings you need. Only how the Lord is going to respond does not concern you anymore. You've been enlightened!
