In the material world, there are good things and better things. First, the radio, then TV showed up and it became colored. Compact discs have displaced vinyl records. Even in the cooking business, you cook something good and someone else comes along to make the same dish a lot tastier. (But I must say that the flavor of the roasted peanuts I once had in a small Guatemalan village can't ever be bettered!) Moving into the intellectual world, we have the same. Certain areas of knowledge are definitely more advanced and a lot more exciting to study. There is great music and there's not-so-great music. In the spiritual realm, the ultimate is definitely God through Christ, for we cannot possibly find anything or anyone more satisfying in making life meaningful and in fulfilling our needs. He is the ultimate and a must-have for all of us ~ the improvement stops there.
Mark 8.36: "What profit is there for one to gain the whole world and forfeit his life?" The way to go: "Gain God and forfeit the world!"
