Thanks in advance!

Please add the following code in your block file Eg:CustomBlock.php

<?php
namespace [vendor_name]\[module_name]\Block;
class CustomBlock extends \Magento\Framework\View\Element\Template
{
    protected $_customerSession;

    public function __construct(
        \Magento\Framework\View\Element\Template\Context $context,
        \Magento\Customer\Model\SessionFactory $customerSession,
        array $data = []
    ) {
        $this->customerSession = $customerSession;
        parent::__construct($context, $data);
    }
  public function isCustomerLoggedIn()
  {
    $customer = $this->customerSession->create();
        if(!($customer->isLoggedIn()))
             return true;
        return false;
  }    
}

?>

and kindly add the following code in your template file

<?php
$checkCustomer = $block->isCustomerLoggedIn();
if($checkCustomer):
   echo "<b>Please Login!! </b>";
endif;
?>

Hope this helps you.
