There is no place other than Exodus 21:22-25 by which we can determine God's definition of HUMAN life and when it begins.
Psalms 139:13-16 suggests otherwise.
You think the Old Testament is now no longer relevant simply because of Jesus' crucifixion??
No, I think the Old Testament
law is no longer
binding because of Jesus' crucifixion. The Old Testament is entirely relevant — because we need it to understand a number of things in the New Testament, and because the apostles used it to show how the many dozens of Old Testament prophecies had been completed with the coming of Jesus and to teach doctrines like salvation by faith alone —, but its law is no longer binding. The Old Testament is still part of the inspired Word of God, but its law served a temporary purpose for the Israelites.
So, under your version of reality, we can thrown out all the Ten Commandments, is that right?
Yes and no, depending on what exactly you mean. We can throw them out as old law that no longer applies; but we cannot throw them out as totally irrelevant today, because they are part of the Israelite history, because they are still part of the inspired Word of God, and because they contain good principles — even though they are no longer binding.
Wow! Good news, people: there is now no longer any sin because our Portuguese friend has declared the Ten Commandments null and void. Wooohooooo!!!
The fact that the Ten Commandments are null and void does not mean that there is no more sin. We have a new law, which sums up, in two commandments, everything we need to know, which is written in Matthew 22:37-40:
‘“Love the Lord your God with all your heart and with all your soul and with all your mind.” This is the first and greatest commandment. And the second is like it: “Love your neighbour as yourself.” All the Law and the Prophets hang on these two commandments.’ Breaking any of these two commandments is sinning. Paul clarifies, in Romans 13:8-10, saying:
‘Let no debt remain outstanding, except the continuing debt to love one another, for whoever loves others has fulfilled the law. The commandments, “You shall not commit adultery”, “You shall not murder”, “You shall not steal”, “You shall not covet”, and whatever other command there may be, are summed up in this one command: “Love your neighbour as yourself.” Love does no harm to a neighbour. Therefore love is the fulfilment of the law.’
Science defines life as when cell division is taking place. Even by scientific terms, that definition is wrong. We know, for instance, that hair and fingernails are composed of cells and that they continue to grow for years after we die.
Then, what do you consider life?
I will remind you of this: "Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfill."- Jesus the Christ, Matt.5:17.
That verse is correct, but it nowhere tells us to obey the Old Testament law. Indeed, we are not supposed to destroy the Ten Commandments, as I have said. They are like a country's law that has been revoked: you are not supposed to destroy it, because there is general interest in archiving it and preserving it for historical reasons; however, you are no longer supposed to abide by it. Similarly, we must not abide by the Ten Commandments, because their purpose has been fulfilled by Jesus (as I have shown, Paul clarifies in Romans 13:8-10), but they are not to be discarded or destroyed.
