I believe I have found the answer to these questions, and I should like to state frankly that my object in writing this book is to try to bring into some troubled Christian lives around me a little real and genuine comfort. My own idea of the religion of the Lord Jesus Christ is that it was meant to be full of comfort. I feel sure any unprejudiced reader of the New Testament would say the same; and I believe that every newly converted soul, in the first joy of its conversion, fully expects it. And yet, as I have said, it seems as if, with a large proportion of Christians, their religious lives are the most uncomfortable part of their existence. Does the fault of this state of things lie with the Lord? Has He promised more than He is able to supply?
A writer has said, “We know what overadvertisement is. It is a twentieth-century disease from which we all suffer. There are posters on every billboard, exaggerations on every blank wall, representations and misrepresentations without number. What visions we have seen of impossible fruits and flowers grown from Mr. So-and-So’s seeds. Everything is overadvertised. Is it the same with the kingdom of God? Do the fruits which we raise from the good seed of the kingdom verify the description given by Him from whom we obtained that good seed? Has He played us false? There is a feeling abroad that Christ has offered in His Gospel more than He has to give. People think that they have not exactly realized what was predicted as the portion of the children of God. But why is this so? Has the kingdom of God been overadvertised, or is it only that it has been underbelieved; has the Lord Jesus Christ been overestimated, or has He only been undertrusted?”
What I want to do in this book is to show, in my small measure, what I firmly believe, that the kingdom of God could not possibly be overadvertised, nor the Lord Jesus Christ overestimated, for eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love Him; and that all the difficulty arises from the fact that we have underbelieved and undertrusted.
