170:2.16

They looked upon the coming of the kingdom in the hearts of men as a gradual development, like the leaven in the dough or like the growing of the mustard seed. They believed that the coming of the kingdom in the racial or world sense would be both sudden and spectacular. Jesus never tired of telling them that the kingdom of heaven was their personal experience of realizing the higher qualities of spiritual living; that these realities of the spirit experience are progressively translated to new and higher levels of divine certainty and eternal grandeur.
