“The sun shall no longer be your light by day, nor for brightness shall the moon give light to you; but the LORD will be to you an everlasting light, and your God your glory. Your sun shall no longer go down, nor shall your moon withdraw itself; for the LORD will be your everlasting light, and the days of your mourning shall be ended” (Isaiah 60.19-20).

The former things will have passed away once the days of mourning end. New Jerusalem will have no need of the sun or of the moon to shine in it, “for the glory of God illuminates it. The Lamb is its light” (Revelation 21.23). God’s “anger is but for a moment, His favor is for life; weeping may endure for a night, but joy comes in the morning” (Ps 30.5). The days of mourning will end.

What’s true for Israel is true for all nations in the end. Light is life and hope while darkness is heavy and dreadful. Once in the light of God’s presence, all earthly sorrow is forgotten. It is true that we can glory in our tribulation here and now, but when Jesus reigns the days of mourning are ended. 

The good gifts coming from above in this present darkness pale in comparison to seeing our God face to face. There will be no need for rest once the days of mourning end. Nothing to worry about. Nothing to trouble over. No confusion. No distress. The days of mourning end. They give way to one eternal Day. 

Joy Comes in the Morning by Frank Garlock:

I trust in God through darkest night,

He faithful will remain;

I’ll trust Him till the morning light

Restores my sight again.

Chorus

Joy will come in the morning,

Hope is sorrow’s adorning;

Tears will vanish at dawning,

For joy will come in the morning.

Our Father leads through sorrows deep,

A cooling spring to make;

Where those who thirst and those who weep

May from that stream partake.

When disappointment breaks my heart,

And tears of sorrow flow;

When troubles come and hopes depart,

God’s promise stands I know.
