Doubt

Soon the lights will glisten and the Sun of Truth will shine with a burning ray in that country. At that time the maid-servants who are firm and constant will rejoice; while every doubtful soul who wavers will regret. Woe unto him, woe unto him, in that day wherein the beloved will attain joy by the surrounding Kingdom of thy Lord, the Precious, the Beneficent!
