Context

“The body of this death spoiled the joy of his spirit. He did not always entertain the sweet and glad expectation of his heavenly inheritance. He often felt miserable. This goes to show how hard it is to believe. Faith is feeble, because the flesh wars against the spirit. If we could have perfect faith, our loathing for this life in the world would be complete. We would not be so careful about this life. We would not be so attached to the world and the things of the world.” source
