Calvin Quote

In studying for a sermon on Ps 109 I ran across this quote from John Calvin. In light of those who would consider Calvinism antithetical to evangelism, consider this:

"As we cannot distinguish between the elect and the reprobate, it is our duty to pray for all who trouble us; to desire the salvation of all men; and even to be careful for the welfare of every individual" (Commentaries, vol. VI, Psalm CIX, p283).

This is consistent with a substantial number of other quotes throughout his commentaries and even the Institutes. We'd do well to listen to Calvin before making assumptions about Calvinists.
