Romans 3:28 Therefore we conclude that a man is justified by faith without the deeds of the law.
James 2:14 What doth it profit, my brethren, though a man say he hath faith, and have not works? can faith save him?
James 2:21 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. 24 Ye see then how that by works a man is justified, and not by faith only.
Have you ever heard of the saying, “There’s nothing new under the Sun.” This is true even of spiritual things. If you read the inspired words from the Holy Spirit from various Gospel writers you can see they addressed some of the same things going on in our day. For example if you read Romans 3 and 4 you’ll see Paul addressed the error of salvation by works, or LEGALISM. Adding something to faith to earn or merit salvation. Salvation by grace through faith never mixes with salvation by works (Romans 11:6). It’s the false idea that divine blessing is given on the basis of human works. The moment works or a single work a man can do to merit his salvation, earn his salvation, or could be credited to have done something for his salvation it ceases to be salvation by grace. It can no longer be salvation by the work Jesus did for man on the Cross. At the Great White Throne Judgment in Revelation 20:11-15 the unsaved person’s works will be found to be insufficient to gain them a place in Heaven and eternity with God.
James the Apostle addressed or corrected the opposite error in James 2. That works are unnecessary after we are saved. This is the error of LAWLESSNESS. This is so common today with some in the name of the “grace message” but the true grace message will produce good works Ephesians 2:10. At the Judgement Seat of Christ the works of a saved person will be judged 2 Corinthians 5:10; 1 Corinthians 3:11-15. Our works after salvation justify us that the original belief in God we exercised was genuine. That is what the scriptures say of Abraham’s faith when he was willing to offer up his son Isaac. His works were proof of his original belief therefore justifying him as having genuine faith or truly believing.
