Although your husband did not exhibit a strong faith in the Lotus Sūtra in this life, perhaps due to meritorious acts in his previous life, he is taking this opportunity of a long illness to become a devotee of the Lotus Sūtra and is trying to practice its teaching. I believe that the minor crimes committed by him may have already dissipated. Even the major evil of his slandering the True Dharma must have been eradicated due to his devotion to the Lotus Sūtra. Even if he should leave this world to go to the Pure Land of the Sacred Mountain right now, he would be as happy as if he were basking in the sunshine, and finally able to see clearly in all directions due to its light. He would rejoice over an early death.
