Was not Abraham our father justified by works when he offered Isaac his son on the altar? James 2:21
Not the works of the law.
Not work that earns a wage.
Not good works.
Abraham was justified by the work or action of obedience;
the obedience of faith.
But now is made manifest, and by the scriptures of the prophets, according to the commandment of the everlasting God, made known to all nations for the obedience of faith:
Romans 2:26
in context....
Faith Without Works Is Dead
Jas 2:14 What use is it, my brethren, if someone says he has faith but he has no works? Can that faith save him?
Jas 2:15 If a brother or sister is without clothing and in need of daily food,
Jas 2:16 and one of you says to them, "Go in peace, be warmed and be filled," and yet you do not give them what is necessary for their body, what use is that?
Jas 2:17 Even so faith, if it has no works, is dead, being by itself.
Jas 2:18 But someone may well say, "You have faith and I have works; show me your faith without the works, and I will show you my faith by my works."
Jas 2:19 You believe that God is one. You do well; the demons also believe, and shudder.
Jas 2:20 But are you willing to recognize, you foolish fellow, that faith without works is useless?
Jas 2:21 Was not Abraham our father justified by works when he offered up Isaac his son on the altar?
Jas 2:22 You see that faith was working with his works, and as a result of the works, faith was perfected;
Jas 2:23 and the Scripture was fulfilled which says, "AND ABRAHAM BELIEVED GOD, AND IT WAS RECKONED TO HIM AS RIGHTEOUSNESS," and he was called the friend of God.
Jas 2:24 You see that a man is justified by works and not by faith alone.
Jas 2:25 In the same way, was not Rahab the harlot also justified by works when she received the messengers and sent them out by another way?
Jas 2:26 For just as the body without the spirit is dead, so also faith without works is dead.
James 2:21-26
James cites three illustrations of living faith: (1) Abraham (Jas_2:21-24); (2) Rahab (Jas_2:25); and (3) the human body and spirit (Jas_2:26).
James 2:21
justified by works. This does not contradict Paul's clear teaching that Abraham was justified before God by grace alone through faith alone (Rom_3:20; Rom_4:1-25; Gal_3:6, Gal_3:11). For several reasons, James cannot mean that Abraham was constituted righteous before God because of his own good works: (1) James has already emphasized that salvation is a gracious gift (Jas_1:17-18); (2) in the middle of this disputed passage (Jas_2:23), James quoted Gen_15:6, which forcefully claims that God credited righteousness to Abraham solely on the basis of his faith (see notes on Rom_1:17; Rom_3:24; Rom_4:1-25); and (3) the work that James said justified Abraham was his offering up of Isaac (Gen_22:9, Gen_22:12), an event that occurred many years after he first exercised faith and was declared righteous before God (Gen_12:1-7; Gen_15:6). Instead, Abraham's offering of Isaac demonstrated the genuineness of his faith and the reality of his justification before God.
James is emphasizing the vindication before others of a person's claim to salvation. James's teaching perfectly complements Paul's writings; salvation is determined by faith alone (Eph_2:8-9) and demonstrated by faithfulness to obey God's will alone (Eph_2:10).
