You look around at what is happening in the world. You see many things that are going wrong all over the place. I'm not going to list any of them. You know what they are. Both, things right near you, and things far away.
Often you have a difficult time determining where the true justice and rightness lies in what is happening. Often you don't know who is right. There seems to be some rightness in everything, even though there is also wrongness. There is the good and bad in everything.
Do you have strength to correct the wrong and the bad like you wish? What strength do you really have? I mean, in your life, just to live, you depend on the activities of some/many other people. Do you grow all your own food? Can you make the car you drive?... or even the bicycle? Do you make your own clothes? Is your water something that is free to you? Can you get rid of the smog in the air you breathe? Can you keep yourself from getting sick? Where do you start?
The answer is that you and I don't have much strength at all. So, we have to use the strength that we have in the best way that we can. The question, again, is: "Where is our greatest strength for changing the world?"
Our greatest strength is in prayer to God. Why? I mean, why would God listen to me? The answer is, because He is way ahead of listening to you already. What?! Here's what.
Can you cause yourself to grow a new arm or hand if you lose one? Can you change the color of your hair by thinking about it? Can you change the color of your eyes? Can you make yourself live longer or healthier by thinking about it? This "stuff" and much more, exists already because God already made it for you.
All that you can do is based on using the things of nature that are around you. And any changes you make are generally not as good as what was there in nature in the first place. But if it they are, it's because nature already seems to have a plan for you to make something as good as what already exists.
Since God set all things in place already, and since He is giving you the food and water and clothing, etc., that you need to live, He is the strength that you need, if you want to change things in the world.
Again, why would He listen to you? Because He has already listened to your basic needs with a wonderful universe to live in... even though there is corruption in it. Since He has listened to your needs long before you even thought about them, and since He is continually listening to many of your needs that you don't even know about, He will certainly listen to your prayers when you call out to Him.
Do you want to change the world, or at least conditions around you that you seem to have no control over? Call to God. Never give up calling. He will hear you even as He is listening to your needs already. And He will make changes for you... if you keep on calling, sincerely, trusting in Him.
