Why "The Book of Martha"?

In the scriptures we read about the life of or the writings of an individual and they title it:  The Book of Jacob, The Book of Ruth, hence . . .  The Book of Martha.  Not that my writings are scripture, but they are a representation of me.  I do have a testimony of Christ and I'd like to think that my joy of such truth comes shining thru in all that I do.

 

"Let your light so shine before men,

that they may see your good works,

and glorify your Father which is in heaven." 

Matthew 5:16
