Actually, not so. This was the whole purpose of the parable of the prodigal son. He was in good standing with his father, he left his father, and when he came back to the father, what did the father say? "My son was dead but now he is alive." He didn't die physically, but spiritually. ("God is the God of the living, not the dead.")
a total misuse of the parable. Its central point was that the prodigal was a sinner from his youth who turned back to God, whereas the elder brother did not seem to have strayed. The one was an example of the tax collectors and sinners, the other an example of the Scribes and Pharisees. When the Father said that the younger son 'was dead', he was not referring to spiritual death, he was saying as far as he was concerned his son had been literally dead.
When we leave the Father, we are spiritually dead.
we are spiritually dead from birth
Jesus said "I tell you the truth, unless you eat of the flesh of the Son of Man (spiritually), and drink His blood, you have no life in you."
He was saying that he who came to Him (ate of Him) and he who believed in Him (drank of Him) (6.35) would neither hunger nor thirst. He added the thought of drinking of His blood, which using OT parallels meant benefitting by His death through faith. The Lord's Supper was not in mind as it was still years away,
Does our heart beat once? No- it beats continuously to supply the whole body with blood- and the Bible says the life is in the blood.
In context this is irrelevant.
It's not enough to get baptized into Christ, you have to continuously partake of the Lords Supper, upon the first day of the week, in the assembly of the church.
we are expected to do so, but neither the literal baptism nor the literal Lord's Supper are essential for our salvation. The Quakers do neither.,
If you leave Christ's body (His church), then you leave Christ, and His blood.
So you think Christ will be maimed and crippled? Once you are a part of His body you are part for life.
If you go back to living in the world, sinning purposely, "there no longer remains a sacrifice for your sins." And "no longer" means there once did, but no longer does. (Hebrews 10:26)
He is talking to Jews who are hovering about whether to become Christians or not. If they wilfully sin there is no longer an OT sacrifice for sin, it is either Christ or judgment. He is speaking about OT sacrifices which he is saying are no longer valid.
