A reason for the laws for a people is that after Adam he caused transgression and sins upon all mankind but something interesting God created him out of all of mankind and he had only one commandment but he obeyed the father's will in part and doing this I believe that is why God was always looking for that one that could obey. But all my bible shows is that there were only 7 faith walkers out of all mankind that had ear to hear, eye to see and heart to obey in the book of genesis. But My God loves everyone one and we needed the laws in the beginning because they that God desired were a faithless and forward generation but his Loves is eternal and his tender mercies and loving kindness succeeds all of time.
Food for thought perhaps the prophets has laws for the people before the perfect law of Christ
Food for thought where does the law of faith come in for the law givers because faith cometh by hearing and hearing by the word of God?
Food for thought did not Jesus do away the law of Moses and full fill the law of Moses when he obeyed his one command to lay down his life that we would all have life full of grace and faith.
The first law giver that heard and was instructed by God was Moses and he had 613 commandments for the people but the thing is if you disobeyed one law it meant you broken all of them there was nothing good about the law if you did not obey all the law .
The second lawgiver was Jesus and below were his two commandments:
And thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind, and with all thy strength: this is the first commandment.
And the second is like, namely this, Thou shalt love thy neighbour as thyself. There is none other commandment greater than these
