Concise Bible Dictionary:

Man is justified by faith apart from the “works of the law” (Rom. 3:2020Therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law is the knowledge of sin. (Romans 3:20); Gal. 2:1616Knowing that a man is not justified by the works of the law, but by the faith of Jesus Christ, even we have believed in Jesus Christ, that we might be justified by the faith of Christ, and not by the works of the law: for by the works of the law shall no flesh be justified. (Galatians 2:16)), but real faith will produce “good works,” and these can be seen of men, though the faith itself be invisible (James 2:14-2614What doth it profit, my brethren, though a man say he hath faith, and have not works? can faith save him? 15If a brother or sister be naked, and destitute of daily food, 16And one of you say unto them, Depart in peace, be ye warmed and filled; notwithstanding ye give them not those things which are needful to the body; what doth it profit? 17Even so faith, if it hath not works, is dead, being alone. 18Yea, a man may say, Thou hast faith, and I have works: show me thy faith without thy works, and I will show thee my faith by my works. 19Thou believest that there is one God; thou doest well: the devils also believe, and tremble. 20But wilt thou know, O vain man, that faith without works is dead? 21Was not Abraham our father justified by works, when he had offered Isaac his son upon the altar? 22Seest thou how faith wrought with his works, and by works was faith made perfect? 23And 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. 24Ye see then how that by works a man is justified, and not by faith only. 25Likewise also was not Rahab the harlot justified by works, when she had received the messengers, and had sent them out another way? 26For as the body without the spirit is dead, so faith without works is dead also. (James 2:14‑26)).
When the Jews were persecuting Christ because He had healed a man on the Sabbath day, He said, “My Father worketh hitherto, and I work” (John 5:1717But Jesus answered them, My Father worketh hitherto, and I work. (John 5:17)). God had rested from His works of creation on the seventh day, but sin had come in, and in the Old Testament allusions are frequent as to the activity of Jehovah for the spiritual blessing of man.
The apostle Paul, in writing to Titus, insists strongly on good works, that Christianity might not be unfruitful.
