Convicting Quote

" 'Tis not for man to trifle.  Life is brief, and sin is here.  Our age is but the falling of a leaf - a droping tear.  We have no time to sport away the hours: all must be earnest in a world like ours.  Not many lives, but only one have we, - one, only one; how sacred should that one life ever be that narrow span!  Day after day filled up with blessed toil, hour after hour still bringing in a new spoil."
