All in Theology
With this foundation the psalmist extols the work of God in history: He will protect His people forever. The word “generation” may here refer to a type of person, the unrighteous who bring destruction. Then this psalm would sing out eternally for the people of God to remember as they see wickedness on “every side” (v. 8). There is nothing to appear in the conclusion when the Lord’s pure word establishes the protection of “us”, the “godly ones” (v. 1), forever.
Perhaps more technical then previous passages, this verse in particular can hold a significant key in understanding the rest of this epistle. It is well known that Paul was not one of the first of the Jewish believers (1 Cor 15:8). There is no reason to believe that Paul here is speaking concerning his place of conversion amongst other Jews.
C.S. Lewis | The Postmillennialist?
However, the sentiment he relays in this quote is one that many postmillennials want to relay in their eschatology.
Put into practical words, God as Creator stands as a Promise to His people of their protection and assurance in righteousness. Any attack against God’s purpose for His people can be equated and symbolized as a destruction of the created order or “the foundations.” And if that can be done, the righteous have no hope (v. 3).
