David Murray was disappointed by aspects of James Hamilton’s well received book God’s Glory Through Judgment, (which he otherwise commends) which he inferred to mean that the Israelites were saved through a mixture of faith, sacrifices and obedience in this post.
In a following post Murray provides his own understanding of the Old Testament sacrificial system and its purpose of pointing out that no amount of animal sacrifices could atone for sin, all they could do was point toward a great sacrifice that God Himself had promised He would provide.
He uses Hebrews 10:1-4 as an outline in the post How many animals will save my soul?
