Brethren and sisters, I wish you to continue in your ways of welldoing; I desire that your minds may be opened more and more to see and understand things as they are. This earth, in its present condition and situation, is not a fit habitation for the sanctified; but it abides the law of its creation, has been baptized with water, will be baptized by fire and the Holy Ghost, and by-and-by will be prepared for the faithful to dwell upon.
