Alexander Maclaren,
Expositions of Holy Scripture: Psalms
“ But if we have that one constant thought with us, and if we are, through all the variety of occupations, true to the one purpose of serving and keeping near God, then we have a charm against the frittering away of our lives in distractions, and the misery of multiplicity; and we enter into the blessedness of unity and singleness of purpose; and our lives become, like the starry heavens in all the variety of their motions, obedient to one impulse. For unity in a life does not depend upon the monotony of its tasks, but upon the simplicity of the motive which impels to all varieties of work. ”
