Abraham's justification was applied in Genesis 15, but that justification was not fulfilled until Genesis 22. That is the point James is making.
21 Was not Abraham our father justified by works, when he had offered Isaac his son upon the altar?
22 Seest thou how faith wrought with his works, and by works was faith made perfect?
23 And the scripture was fulfilled which saith, Abraham believed God, and it was imputed unto him for righteousness: and he was called the Friend of God.
James is showing us that Genesis 15:6 was not fulfilled until Abraham offered up Isaac. Remember mailmandan, that the one Abraham was proving himself to on top of that mountain was God. He was not justified before men up there as most commenters falsely claim. On that mountain God said, "now I KNOW that thou fearest God, SEEING thou hast not withheld thy son, thine only son from me." Genesis 22:12
The question James is asking in James 2 is not "will works follow faith?" The question is "can faith save him?". James 2:14
Paul makes it clear that the faith that saved me has no works attached to it whatsoever. In fact, the faith that saved me was not my faith, but the faith of Jesus Christ! Abraham did not have the faith of Christ. It wasn't even available to him according to Paul in Galatians 3.
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 word "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),
not the initial act of being accounted as righteous with God (Romans 4:2-3). Works bear out the justification that already came by faith.
In the Strong's Exhaustive Concordance of the Bible, the Greek word for justified "dikaioo" #1344 is:
1. to render righteous or such he ought to be
2. to show, exhibit, evince, one to be righteous, such as he is and wishes himself to be considered
3. to declare, pronounce, one to be just, righteous, or such as he ought to be
In Matthew 12:37, we read - "For by your words you will be
justified, and by your words you will be condemned." This is because our words (and our works) reveal the condition of our hearts. Words/works will appear to be evidences for, or against a man's being in a state of righteousness.
God is said to have been
justified by those who were baptized by John the Baptist (Luke 7:29). This act pronounced or declared God to be righteous. It did not make him righteous. The basis or ground for the pronouncement was the fact that God IS righteous. Notice that the NIV reads,
"acknowledged that God's way was right.." The ESV reads,
"they declared God just.." This is the sense in which God was justified,
"shown to be righteous".
Matthew 11:19 "The Son of Man came eating and drinking, and they say, 'Behold, a gluttonous man and a drunkard, a friend of tax-gatherers and sinners!' Yet wisdom is
justified/vindicated/shown to be right by her deeds."
