The tone of William Blake's poem "The Lamb" can be best conveyed as innocent. The lamb is a child poem in two stanzas.
The first stanza is descriptive and rural whereas, the second stanza contains analogy and explanations.
The lamb in the poem symbolizes the Jesus. It underscores the Christian values of peace, gentleness, and meekness. Also, the image of a child in the poem is also associated with that of Jesus. Like many of 'songs of innocence' the positives of the aspects of conventional Christian belief seen by Blake are accepted.
