Blessings from God.
“May the peoples praise you, God:
may all the peoples praise you.
The land yields its harvest;
God, our God, blesses us.
May God bless us still,
so that all the ends of the earth will fear him.”
We know that the sun shines and the rain falls on both the righteous and the unrighteous (Mt. 5:45). But here the psalmist was speaking in general terms, meaning that those who serve the Lord will be more productive and enjoy more blessings than those who do not.
