From Buddhism's Sacred Scripture: The Sutra of the Lotus of the Wonderful Dharma, Chapter 3, Part 7 of 8

If you and the others are capable of believing and accepting my words, then all of you are certain to attain the Buddha way. This vehicle is subtle, wonderful, foremost in purity; throughout all worlds it stands unsurpassed. “I tell you, Sariputra, you and the others are all my children, and I am a father to you. For repeated kalpas you have burned in the flames of manifold sufferings, but I will save you all and cause you to escape from the threefold world.” This Lotus Sutra is preached for those with profound wisdom.
