What is the meaning of tears of repentance?

The weary wanderer who reaps a harvest of repentant tears

Should cast aside such sad unhappy fears―

They cannot help, nor lead him on

As loving God has ever done―

They cannot make him see the Light,

For they but blind the mortal sight,

And hinder hope and dim that light

Which could shine forth so clear and bright,

Were it made welcome with pure delight.
