You created the north and the south; Tabor and Hermon sing for joy at your name. Psalm 89:12
The psalm writer wanted to let the readers know that one day all four corners of the world will rejoice in His name. It is a restatement of the previous verse.
We see the world in shambles now (politically, economically, spiritually) but it will not always be like that. And it may very well get worse before it gets better. But the point is that God is still in control of world events and is still on the throne.
Yes, there are Believers on all four corners of the planet that do praise Him now, but it’s not over yet. Rejoice that the Church continues to grow throughout the world, but also know that many Believers are going through intense persecution as they hold to their faith. Pray as if their lives depend on it.
In many cases, it does.
