There are a lot of people who would like to know the difference between strength and power mainly because they know that both are needed right now. When you have enough strength, this means that you can do things that the weak cannot do.
It does not have to be just limited to physical strength. You can be mentally strong or you can be very strong in terms of emotions as compared to other people.
When you say power, this means that you have influence over other people because you know that you can do different things. Power can be gained from doing different things or achieving different things.
