Our tendency as humans is the opposite. We have no power, we think we can change the world, and we spend most of our time building huge organizations and legacies.
Just think, if we all lived a long time, spoke the same language were unified as citizens of Earth, put aside our differences and just see what we could accomplish! That reminds me of the Tower of Babel in the Bible. God had to "come DOWN" to man's greatest achievement in history.
God apparently believes that the best use of our time is investing ourselves in others on a very small scale so the investment is meaningful. He modeled it, then told us to do it. Go make Disciples.
