Shakespeare's Sonnets: Love is too young to know what conscience is

Love is too young to know what conscience is,Yet who knows not conscience is born of love?Then, gentle cheater, urge not my amiss,Lest guilty of my faults thy sweet self prove.For thou betraying me, I do betrayMy nobler part to my gross body's treason;My soul doth tell my body that he mayTriumph in love; flesh stays no farther reasonBut rising at thy name doth point out theeAs his triumphant prize; proud of this pride,He is contented thy poor drudge to be,To stand in thy affairs, fall by thy side. No want of conscience hold it that I call Her "love" for whose dear love I rise and fall.
