Four questions for Christians

[Dionysius]

The Jews needed no urging to take revenge on their enemies. It was their imperfect standard. Hypothetically, having mercy on one of these people would have been progressive at the time. But this never happened. God acted according to their standard and weaned them off of it, completing the act with Christ. In the same way, Christ followed Jewish laws only to tell the Jews later that they were not salvation in themselves. The punitive justice of these soldiers was inherently good, but they had to be taught to stop doing it themselves and leave it to God.
The killing of these women and children could have been a coup de grace to the Amalekite nation, as the men had to be killed, but the women and children they left behind were vulnerable to the desert climate and foreign tribes.

Then sin or what is considered wrong is entirely relative to the time or age? Is this what you are trying to say in an overly wordy and confusing way?

God was telling his people to lose confidence in their labor and restore it in him.

Go only required man to have confidence in him one day per week? Is the day of the week, in which the Sabbath is observed, even relevant? Has it gone by the way of relativity the same as the law?

The laws coincided with the Jewish culture. Pigs, for example, could have been considered as dirty animals.

Again, so the law itself was incidental and merely a device to gauge a believers obedience to God? Is that it?
