John 3:16 and Luke 9:23 have to go together in order for there to be an accurate understanding of the gospel’s invitation. John 3:16 emphasizes believing. Luke 9:23 focuses on following. Those two things must necessarily go together. There is no believing without following. There is no John 3:16 without Luke 9:23.
