Watching the weather news about a recent hurricane, I heard the term "the cone of uncertainty" to describe the possible but unpredictable trajectory of a storm. I was reminded of it with a quote in my prayer book on the hope that all things will be brought to God in the end. That is an older world-view that projects a "cone of certainty" in which everything will work out according to God's "goal"--a teleology of seeing how everything comes together in the end.
A perspective more understandable to the contemporary mind might be to refer to the "cone of indeterminacy" -- it may sound better than "uncertainty" and it rings true with quantum physics. Rather than seeing all things coming to a pre-determined end, even God's end, we see trajectories of freedom and choice with lives evolving and changing as they go along. The picture of fractals, lovely and complex patterns of developing reality, but not predictable in their outcomes. This is a "process theology" approach, it seems to me.
We can found our hope, as Christians, not in certainty but in the sense that God is luring us all, including the whole cosmos, into newer and more whole ways of being.
