John Calvin Commentary Psalms 37:29

"The righteous shall inherit the land, And dwell therein for ever." — Psalms 37:29 (ASV)

The righteous shall inherit the earth. The repetition of this same doctrine here is not superfluous, since it is so very difficult to impress it deeply upon our minds.

For while all people seek happiness, scarcely one in a hundred looks for it from God. Instead, by making provision for themselves, they all provoke God’s vengeance, as it were deliberately, and strive to excel one another in doing so. Consequently, some stain themselves with fraud and perjury, others indulge in robbery and extortion, some practice all sorts of cruelty, and still others commit violence and outrage, even with the sword and poison.

Moreover, I have, just now and on several other occasions, stated the sense in which this everlasting habitation on the earth, which is promised here to the righteous, is to be understood. Namely, although they are surrounded by the troubles and changes that occur in this world, God still preserves them under his wings; and although there is nothing lasting or stable under heaven, he still keeps them in safety, as if they were sheltered in a secure haven.

And, finally, in addition to this, they enjoy that inward peace of mind which is better than a hundred lives, and which is therefore justly regarded as a privilege surpassing all others in value and importance.
