Faith in Jesus Christ alone for salvation is sufficient to save because the OBJECT of our faith (Jesus Christ and His finished work of redemption) is sufficient to save us. (Romans 3:24-26) But apparently not sufficient for you which explains why you turn to supplements. You seem to believe completion means completion in finally being able to save. You misunderstood James 2:22.
In James 2:22, faith made perfect or complete by works means bring to maturity, to complete like love in
1 John 4:18. It does not mean that Abraham was finally saved based on merits of his works after he offered up Isaac on the altar in Genesis 22. When Abraham performed the good work in Genesis 22; he
fulfilled (vs. 23)
the expectations created by the pronouncement of his faith in
Genesis 15:6.
In James 2:21, notice closely that James does not say that Abraham's work of offering up Isaac resulted in God accounting Abraham as righteous. The
accounting of Abraham's faith as righteousness was made in
Genesis 15:6, (also see
Romans 4:2-3)
many years before his work of offering up Isaac recorded in Genesis 22. The work of Abraham did not have some kind of intrinsic merit to account him as righteous, but it
showed or manifested the genuineness of his faith. (
James 2:18) That is the "sense" in which Abraham was "justified by works." (
James 2:21) He was
shown to be righteous.
So according to your misunderstanding about completion, Abraham would have remained a lost man in Genesis 15:6 when he believed in the Lord and it was credited to him for righteousness, until many years later, after he offered up Isaac on the altar in Genesis 22.
