The Law of Moses was put in place to guide the people of Israel. They had no other choice but to try to follow the Law because it was the only way to stay in communion with our perfect God. But the Law was hard and it was impossible to keep fully and to the extent required by God. It was for this reason Christ died on the cross for us; to give us a way to God provided by grace. In Acts 15:10-11 Peter spells this out, 10 Now then, why do you try to test God by putting on the necks of the disciples a yoke that neither we nor our fathers have been able to bear? 11 No! We believe it is through the grace of our Lord Jesus that we are saved, just as they are. It is a simple process to believe and yet we all know it is conceptually difficult for some. It all comes down to trust and faith in the love Christ has for us all.
