Analysis of A Hymn To God The Father

Wilt thou forgive that sin where I begun,
         Which was my sin, though it were done before?
     Wilt thou forgive that sin, through which I run,
         And do run still, though still I do deplore?
             When thou hast done, thou hast not done,
                 For I have more.

Wilt thou forgive that sin which I have won
         Others to sin, and made my sin their door?
     Wilt thou forgive that sin which I did shun
       A year or two, but wallow'd in, a score?
           When thou hast done, thou hast not done,
               For I have more.

I have a sin of fear, that when I have spun
       My last thread, I shall perish on the shore;
   But swear by thyself, that at my death thy Son
       Shall shine as he shines now, and heretofore;
           And, having done that, thou hast done;
               I fear no more.
