Charles Hodges said:
The great difficulty with many Christians is that they cannot persuade themselves that Christ (or G0d) loves them; and the reason why they cannot feel confident of the love of God, is, that they know they do not deserve his love, on the contrary, that they are in the highest degree unlovely. How can the infinitely pure God love those who are defiled with sin, who are proud, selfish, discontented, ungrateful, disobedient? This, indeed, is hard to believe.
