An orange tree produces oranges just as faith produces fruit/works. An orange tree does not produce oranges in order to become a living tree, but because it's a living tree and it's the same with faith and works. Life flows through the root and produces the fruit.
In regard to "faith without works is dead" in James 2:20, James does not mean that works are the source of life in faith or that we are saved by works. James is simply saying faith that is not accompanied by evidential works
demonstrates that it's dead. If someone merely
says-claims they have faith, but lack
resulting evidential works, then they
demonstrate that they have an
empty profession of faith/dead faith and not authentic faith. (
James 2:14)
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,
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. That is the "sense" in which Abraham was "justified by works." He was
shown to be righteous.
In James 2:22, faith made perfect or complete by works means bring to maturity, carry to the end, to complete like love in 1 John 4:18. It doesn't 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 the expectations created by the pronouncement of his faith in Genesis 15:6.
In James 2:23, the scripture was
fulfilled in vindicating or demonstrating that Abraham believed God and was accounted as righteous. Abraham was
accounted as righteous based on his faith (Genesis 15:6)
not his works (Romans 4:2-3) long before he offered up Isaac on the altar in Genesis 22.
In James 2:24, James is not using the term "justified" here to mean "accounted as righteous" but is
shown to be righteous. James is discussing the
evidence of faith (says-claims to have faith but has no works/I will show you my faith by my works -
James 2:14-18) and
not the initial act of being accounted as righteous with God. (
Romans 4:2-3)
In James 2:25, Rahab believed in the Lord with authentic faith (
Joshua 2:9-13), requested "kindness" (2:12), received the promise of kindness (2:14), and hung out the "scarlet line" (2:21), as the
demonstration of her authentic faith. She
showed that her faith in God was not a dead faith by her works, just as all genuine believers show theirs.
In James 2:26, the comparison of the human spirit and faith converge around their modes of operation. The spirit (Greek pneuma) may also be translated "breath." As a breathless body
exhibits no indication of life, so fruitless faith
exhibits no indication of life. The source of the life in faith is not works; rather, life in faith is the source of works. (
Ephesians 2:5-10)
