John Piper:

Beholding glory begs for lingering. The modern, fast-paced world will tempt you to rush and skim. This kind of life will make you shallow. The world does not need more widely read, shallow people. It needs deep people. I don’t mean complex. I don’t mean educated. I don’t mean you know big words. I don’t mean you know historical background. I mean you have seen glory – the glory of God in His Word. You have pondered it and felt its relation to all the parts of your life. You have been steadied and satisfied by it. You have come home. You are not frantic anymore. You are at peace in the presence of God. This is what I mean by deep. This is what the world needs. (The Pleasures of God, p. XVIII).
