"I will honour Christmas in my heart, and try to keep it all the year. I will live in the past, the present, and the future. The Spirits of all three shall strive within me. I will not shut out the lessons that they teach. Oh, tell me I may sponge away the writing on this stone!"
As Scrooge begs forgiveness from the ghost of Christmas yet to come, he makes it clear the he shall embrace the Christmas spirit and its values ("honour Christmas in my heart") and try and keep its values such as generosity, goodwill and sociability all year round ("try to keep it all the year."). Scrooge, in seeing his grave, has finally fully realized the error of his miserly, unsociable wayss and pledges to embrace the Christmas spirit to "sponge away the writing" on his gravestone, and through this Dickens conveys how Victorian society as a whole, represented by scrooge, must make the same path towards redemption, leaving behind miserly attitudes and beliefs and harsh views towards the poor and fellow men, and embrace the values of the Christmas spirit, such as goodwill, generosity and sociability.
