Eternity, if you will, is God sitting on the edge of God's chair, waiting for whatever glory or joy or disappointment will come next. Eternity means that God is waiting, and that God has been waiting all along, for certain things to happen when the right moment comes along. It's God waiting for the right moment, the moment when the right person is there, the moment when someone can see, the moment when a healing can take place, the teachable moment, the opportune moment. And eternity is also God waiting for us to respond as well. If you read the Bible, you'll see that it's a record of God waiting for people to turn back, to be faithful, to come to their senses, to rediscover God, or to decide to follow.
Eternity means that some things are changing all the time.
Leaders and laws change. Social conditions, the rise and fall of nations, all of the individual injustices and problems that make up our daily lives. And those things all matter. But from God's point of view, and from the Christian's point of view, in a way all those things are like the weather. Some days are better than others.
