The lessons also go through the sixth chapter of The Gospel of John, in which Jesus lays out the hard stuff that nobody, Christian or not, likes to engage,
"Do not work for the food that perishes, but for the food that endures for eternal life, which the Son of Man will give you. For it is on him that God the Father has set his seal." Then they said to him, "What must we do to perform the works of God?" Jesus answered them, "This is the work of God, that you believe in him whom he has sent."
These and other words are so scandalous that the Gospel itself admits that they repelled rather than attracted,
Because of this many of his disciples turned back and no longer went about with him.
The breakdown of Western cultural Christianity means that those of us who want to be disciples will have to take on more of these hard lessons. The padding of nominalism isn't thick enough to absorb the blows that are to come.
