Our scientific power has outrun our spiritual power. We have guided missiles and misguided men. (Martin Luther King, 20th century civil rights leader)
Each decade seems to bring to light more discoveries and advances in science and technology, and we can hardly keep up with it all. You might think that, as a result, life would be easier and our advances would make us better people. Unfortunately, as King implies, physical improvements have not been matched by spiritual and moral growth.
Like newborn babies, crave pure spiritual milk, so that by it you may grow up in your salvation (1 Peter 2:2).
