"I am very glad to think that you will be with us. Your dear mother's spirits are not always the most buoyant, and, coming first to reside in a large, new house without having some of her children around her, would be very likely to infuse a secret melancholy which might sadden the whole scene, and even produce, by permanent association, a lasting impression of despondency. I finish this letter after hearing an excellent sermon from Robert Hall. It was not merely an exhibition of powerful intellect, but of fervent and feeling piety, especially impressing on his hearers to live by the faith of the love of Christ daily, habitually looking to Him in all His characters. Prayer, prayer, my dear Samuel; let your religion consist much in prayer. May you be enabled more and more to walk by faith and not by sight, to feel habitually as well as to recognise in all your more deliberate calculations and plans, that the things that are seen are temporal, but the things that are not seen are eternal. Then you will live above the world, as one who is waiting for the coming of the Lord Jesus Christ."[54] "_April 20, 1826._ "I would gladly fill my sheet, yet I can prescribe what may do almost as well. Shut your door and muse until you fancy me by your side, and then think what I should say to you, which I dare say your own mind would supply." "_September 30._ "I am thankful to reflect that at the very moment I am now thinking of you and addressing you; you also are probably engaged in some religious exercise, solitary or social (for I was much gratified by learning from a passage in one of your letters to your mother that you and Anderson went through the service of our beautiful liturgy together). Perhaps you are thinking of your poor old father, and, my dear boy, I hope you often pray for me, and I beg you will continue to do so.
