If manifest rights be invaded or denied, he is hereby applied to for the vindicating of what is just and the punishing of wrong. As the sword of justice was made for lawless and disobedient persons (1 Timothy 1:9), so was the sword of war made for lawless and disobedient princes and nations. In war therefore the eye must be ever up to God, and it must always be thought a dangerous thing to desire or expect that God should patronise unrighteousness.
