Violence in the Psalms? What about the NT? What about consequences today for ill-behaviour? Yes there are consequences. We are not into cheap grace or dissembling as are certain prominent persons in my country at present, whether they admit it or not.
Here is a review of a suggestion in a book by David Neville, A Peaceable Hope: Contesting Violent Eschatology in New Testament Narratives, that we quarantine the violence of the NT. Read the argument there. I have a simple conclusion: if we are to be like Jesus, then as in the psalms, there is no warrant in the text to take violence into our own hands.
