I'm reposting here something I previously posted on another thread because it is relevant to this discussion.
One must put the James passage into it's context to get a proper understanding of the teaching of that verse. Abraham had been justified by faith many years before the time that he offered up Isaac.
Genesis 15:5, 6
And he brought him forth abroad, and said, Look now toward heaven, and tell the stars, if thou be able to number them: and he said unto him, So shall thy seed be.
And he believed in the LORD; and he counted it to him for righteousness.
Paul comments upon this in Romans 4:2-5,
For if Abraham were justified by works, he hath whereof to glory; but not before God.
For what saith the scripture? Abraham believed God, and it was counted unto him for righteousness.
Now to him that worketh is the reward not reckoned of grace, but of debt.
But to him that worketh not, but believeth on him that justifieth the ungodly, his faith is counted for righteousness.
Abraham was justified entirely by faith, without the addition of works according to Paul. Paul goes on to explain that if it is by faith, then it cannot involve works in any way. Romans 11:6 says,
And if by grace, then is it no more of works: otherwise grace is no more grace. But if it be of works, then is it no more grace: otherwise work is no more work.
Grace and works cannot coexist as regards salvation. It is either one or the other. This fact has brought about confusion as regarding the teaching of James. It appears to many that Paul and James contradict each other. But this is not the case.
James is speaking of a different portion of Abraham's life than Paul. James is speaking of that instance wherein Abraham offered up his son Isaac.
James 2:20-24
But wilt thou know, O vain man, that faith without works is dead?
Was not Abraham our father justified by works, when he had offered Isaac his son upon the altar?
Seest thou how faith wrought with his works, and by works was faith made perfect?
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.
Ye see then how that by works a man is justified, and not by faith only.
Paul is speaking of a time many years earlier when Abraham received the promise from God for a son, and believed it. This faith justified Abraham according to Paul. James is speaking of a day many years later when Abraham was called upon to offer the son God had promised. Think about what that entailed. God had promised Abraham a multitude of descendants through Isaac. If he killed him before he could start a family, then how could God fulfill the promise? So Abraham's act of offering, or 'work' was a visible demonstration of the reality of Abraham's faith. Hebrews 11:17-19 says,
By faith Abraham, when he was tried, offered up Isaac: and he that had received the promises offered up his only begotten son,
Of whom it was said, That in Isaac shall thy seed be called:
Accounting that God was able to raise him up, even from the dead; from whence also he received him in a figure.
Do you see that Abraham's actions proved the reality of the faith that justified him? Had he not have had such strong faith in God's promises, he would not have offered his son. The 'work' was a natural conclusion of the faith. In other words, if someone has true faith, they will act upon that faith. Faith that does not spur one to act upon it is not faith at all.
So, Abraham's faith in God's promise justified him before God, while Abraham's act of offering Isaac justified Abraham before men, in proving that his faith was real. Notice that this is the context in which James speaks, showing one's faith to be real before men. James 2:18,
Yea, a man may say, Thou hast faith, and I have works: shew me thy faith without thy works, and I will shew thee my faith by my works.
The lesson here is that saving faith will spur someone to do good works. If a person's faith does not spur one to action, then one cannot say that they really have faith. A person only acts upon what he really believes. So faith in Christ alone saves us, and that faith will spur us unto good works. Good works are the fruit of saving faith.
Ephesians 2:8-10
For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
Not of works, lest any man should boast.
For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them.
Notice here that works plays no part in our salvation, but we are saved unto good works, that our faith should produce a walk. So the idea contained in James and Paul is that you are justified by faith alone, but saving faith will spur you to good works.
I remember you posting this and it is just as realavent now as ever!
