"The means by which we live have outdistanced the ends for which we live. Our scientific power has outrun our spiritual power. We have guided missiles and misguided men"

This quote by Martin Luther King Jr. talks to the disconnect between our technological developments and our spiritual development. He is saying that our methods of living have actually exceeded our objectives and aspirations. We have actually ended up being so concentrated on the material and scientific aspects of life that we have actually neglected our spiritual advancement. We have produced effective weapons and tools, but we have actually stopped working to utilize them responsibly. We have become so focused on the physical world that we have actually lost sight of the spiritual world. We have become misguided in our actions and have actually stopped working to use our power for great. King is warning us that if we do not put in the time to concentrate on our spiritual development, we will continue to be misdirected and our clinical power will be lost.
