Please, please, please address scripture. Maybe you have an valid explanation. Maybe I have interpreted them incorrectly. Again, I had an explanation for your verses ... maybe I am wrong. The ball is in your court ... I gave a lot of verses, just address the first 3. Tell me how a verse stating, "a man not justified by works of Law" does not contradict the question at hand, "obeying the Lord and His Commandments required for salvation"
Because the works of the law is not the obedience of faith.
The law is not of faith.
Yet the law is not of faith, but “the man who does them shall live by them. Galatians 3:12
The works of the law of Moses was much more than the 10 Commandments.
Their were animal sacrifices, Sabbath requirements, physical circumcision, feast days to be carefully observed, ceremonial washings, and on and on and on....
When we obey the Gospel, Jesus is our Lord, the One we are to obey.
IOW, in the example I gave from James, Abraham heard God and directly responded to Him in obedience.
Thats how faith comes to us, by hearing God.
Abraham walked in obedience to His Voice and kept His commandments and laws by faith, because He learned directly from the Lord, in which the Lord imparted grace to Him to be able to do what he heard.
Grace is the Holy Spirit; the Spirit of grace.
When we walk in relationship with Him and hear Him speak to us we receive faith and grace from Him.
This is how He designed Adam to live and fulfill His purpose, by learning directly from Him, being filled with His Life everyday.
Partaking of the tree of life; Jesus Christ the Lord
Not so with the law of Moses. The children of Israel didn’t want to hear His voice.
Then they said to Moses, “You speak with us, and we will hear; but let not God speak with us, lest we die.” Exodus 20:19
