Lincoln writes to his step-brother John D. Johnston, of Charleston, Illinois, about Lincoln's father Thomas, who is gravely ill. Lincoln explains that his work and his wife's "baby-sickness" prevent him from being with his father. Lincoln "is doubtful whether it would not be more painful than pleasant" for him and Thomas to "meet now." Lincoln reminds Johnston to "use my name, if necessary, to procure a doctor, or any thing else for Father." He asks Johnston to remind Thomas to "confide in, our...merciful Maker; who will...not forget the dying man, who puts his trust in Him." Abraham Lincoln to John D. Johnston, 12 January 1851, CW, 2:96-97.
