I am setting error message using below code.

$this->_messageManager->addError(__('you must login to continue.'));

Is it possible to load the message from the static block content.

for example i created static block with some html content. that content i need to show in error message. Is that can be done?

you need to try this code.

For phtml file you need to used this code.

$customerror = $block->getLayout()->createBlock('Magento\Cms\Block\Block')->setBlockId('block_identifier')->toHtml();

For block file you need to do code like this.

class Yourclass
    protected $cmsblock;

    public function __construct(\Magento\Cms\Block\Block $cmsblock)
       $this->cmsblock = $cmsblock;

    public function Yourfunction()
      $customerror = $this->cmsblock->setBlockId('block_identifier')->toHtml();

Replace 'block_identifier' with your block identifier.
