Charles H. Spurgeon on Psalms 74:20

1. The title given to heathen nations: dark places of the earth. Not without the light of nature, or of reason, or of natural conscience, or of philosophy, as of Greece and Rome; but without the light of revelation.

2. Their condition: full of, etc.: cruelty in their public, social, and private relationships. See Romans 1: "without natural affection, implacable, unmerciful."

3. Their part in the covenant. This is known from their part in its promises, and in prophecies: I will give thee the heathen, etc.

4. The prayer of others on their behalf: Have respect, etc.; Oh send forth thy light, etc.

The conversion of the world will be in answer to the prayers of the church.
