It is said that in our lifetime most of us use only 3 or 4 percent of their mental capacity and potential ability while living on earth. So, some say human beings have a latent yet limitless capability. At the same time, it tells us that humans are able to use only a small part of the brain God made for them and as creatures, there are limitations placed on us. But when we believe in and rely on God the Creator we can experience the limitless power of God because He makes possible those things that otherwise seem to be impossible.
"'If You can?' All things are possible to him who believes." (Mark 9:23)
