Comparing James with Paul on justification
James writes: Was not Abraham our father justified by works, when he had offered Isaac his son upon the altar? James 2:21
Paul writes: What shall we say then that Abraham our father, as pertaining to the flesh, hath found? 2. For if Abraham were justified by works, he hath whereof to glory; but not before God. 3. For what saith the scripture? Abraham believed God, and it was counted unto him for righteousness. Rom. 4:1-3
How can we harmonize James and Paul on the subject of justification?
It is critical to note that Abraham was justified by faith before God not only prior to the giving of the law but also prior to offering Isaac on the alter, and actually even before Isaac was conceived. Genesis. 14:6
The solution then is that Paul was talking about justification before God, while James was talking about justification before men. “Show me thy faith by thy works,” says James, “let thy faith be justified in the eyes of those that behold thee by thy works;” but Paul speaks of justification in the sight of God, who justifies those that believe in Jesus, purely on account of the redemption that is in him.” Thus we see that persons are justified before God by faith, but faith is justified before men by works.
CONCLUSION: Genuine faith is invisible to all but God. Visible works alone can demonstrate to others that a person is truly justified. Works alone can attest to whether faith is genuine i.e., saving or justifying faith. However works are not the basis of salvation but rather the product of salvation.
