Arise, shine, for your light has come,
and the glory of the LORD rises upon you.
See, darkness covers the earth
and thick darkness is over the peoples,
but the LORD rises upon you
and his glory appears over you. Isaiah 60:1-2
In Isaiah 59:9 the righteous among God’s people expressed their desire for light, though they lived in darkness. Now God announces the arrival of the light, whose source is the glory of God. Darkness will cover the earth (a reference to pervasive sin), but God’s hovering glory will illuminate the way for his people. How has light penetrated the darkness? Through the action of the divine warrior described in Isaiah 59:17-21:
He put on righteousness as his breastplate,
and the helmet of salvation on his head;
he put on the garments of vengeance
and wrapped himself in zeal as in a cloak.
According to what they have done,
so will he repay
wrath to his enemies
and retribution to his foes;
he will repay the islands their due.
From the west, people will fear the name of the LORD,
and from the rising of the sun, they will revere his glory.
For he will come like a pent-up flood
that the breath of the LORD drives along.
“The Redeemer will come to Zion,
to those in Jacob who repent of their sins,”
declares the LORD.
“As for me, this is my covenant with them,” says the LORD. “My Spirit, who is on you, will not depart from you, and my words that I have put in your mouth will always be on your lips, on the lips of your children and on the lips of their descendants—from this time on and forever,” says the LORD.
