Romans 10:5 Moses writes this about the righteousness that is by the law: “The person who does these things will live by them.”
How do you live your life? Do you live it according to the laws of the land, the laws of the Torah, or are you looking for something else?
In the early days when Moses was given charge of teaching the people of Israel how they should be living, he had to teach them a new way to bring them back in line with what God had in mind.
But, people being people, they tried to stick to those rules above all else and hence got tied into that way of living.
Jesus wants us to live in a relationship with Him whereby we do our best and He makes the way forward for us!
