What president ever said in his speeches that our real trouble is sin? All other ailments are suggested, and countless remedies are proposed, but what national leader ever names the basic malady? We try to mop the floor while we leave the faucet running. Anybody with his eyes half open and a Bible in hand ought to be able to diagnose our disease. This is not the exclusive prerogative of theologians. All other trouble is due to heart trouble. We are sinners and something must be done about sin. Something has been done by God in Christ but men will not accept the diagnosis and take the treatment. We must do something about the sin and the Saviour, for the two supreme issues are the sin question and the Son questions.
