was grabbed by this in the NYT today: The Sun Is the Best Optometrist

In short, the biological mechanism that kept our vision naturally sharp for thousands of sunny years has, under new environmental conditions, driven visual development off course. This capacity for previously well-adapted genes to be flummoxed by the modern world can account for many apparent imperfections. Brain wiring that effortlessly recognizes faces, animals and other symmetrical objects can be thrown off by letters and numbers, leading to reading difficulties. A restless nature was once helpful to people who needed to find food sources in the wild, but in today’s classrooms, it’s often classified as attention deficit hyperactivity disorder. When brains that are adapted for face-to-face social interactions instead encounter a world of e-mail and Twitter — well, recent headlines show what can happen.

Luckily, there is a simple way to lower the risk of nearsightedness, and today, the summer solstice — the longest day of the year — is the perfect time to begin embracing it: get children to spend more time outside.

In form the song is a victory hymn, a song sung to and about God in praise of His granting victory to His people over their foes.

The ingredients of Israelite hymns may almost always be summarized by the initials SRR:
Summons to praise,
Reasons to praise,
Recapitulation.

All three elements are present in abundance in the Song of Moses.

–-Douglas Stuart, Commentary on the Book of Exodus

Douglas Stuart:
So important did the song of Exodus 15 become to all generations of believers that it is described in John’s great apocalyptic vision as a song to be sung even in heaven. they sing the song of Moses, the servant of God, and the song of the Lamb, saying,

“Great and amazing are your deeds,
O Lord God the Almighty!
Just and true are your ways,
O King of the nations!
Who will not fear, O Lord,
and glorify your name?
For you alone are holy.
All nations will come
and worship you,
for your righteous acts have been revealed.” Revelation 15:3-4

I’m excited to restart preaching Exodus on Sunday June 26.  We’ll be looking at the song in chapter fifteen.
