The once saved issue reminded me of the Angel called Lucifer, who Jesus saw fall from heaven.
Also when he spoke of the seeds falling on the ground, depicting different ways people can fail , this implies that you are not saved universally. We have to run the race until we die, Paul said. And sin can be forgiven, but first we have to accept that we sin daily, and ask forgiveness.
The Parable of the Sower
1That same day Jesus went out of the house and sat by the lake. 2Such large crowds gathered around him that he got into a boat and sat in it, while all the people stood on the shore. 3Then he told them many things in parables, saying: “A farmer went out to sow his seed. 4As he was scattering the seed, some fell along the path, and the birds came and ate it up. 5Some fell on rocky places, where it did not have much soil. It sprang up quickly, because the soil was shallow. 6But when the sun came up, the plants were scorched, and they withered because they had no root. 7Other seed fell among thorns, which grew up and choked the plants. 8Still other seed fell on good soil, where it produced a crop—a hundred, sixty or thirty times what was sown. 9Whoever has ears, let them hear.”
