Salvation by faith
Judah is to be “saved by faith” from Moab and Ammon, as the Christian is delivered by faith from sin and its penalty. The incident might almost seem to have been recorded in order to illustrate the truth that Paul was to teach. It is strange that there is no reference to this chapter in the Epistles of St. Paul and St. James, and that the author of the Epistle to the Hebrews does not remind us how “by faith Jehoshaphat was delivered from Moab and Ammon.” (W. H. Bennett, M.A.)
God-fearing makes grand soldiers
Carlyle has taught the present generation many lessons, and one of these is that “God-fearing” armies are the best armies. Before his time people laughed at Cromwell’s saying, “Trust in God and keep your powder dry.” But we now know that the trust was of as much use as the powder, if not of more. That high concentration of steady feeling makes men dare everything and do anything. Those kinds of morals and that kind of religion which tend to make the firmest and most effectual character are sure to prevail, all else being the same; and creeds or systems that conduce to a soft limp mind tend to perish, except some hard extrinsic force keep them alive. Strong beliefs win strong men, and then make them stronger. (J. Bagehot.)
