Of course James would never disagree with Jesus, or Paul, or John, or Peter, et al. And if they ever did they would sit down and iron things out. In any case I can reconcile all your verses with the following becauase I know the role and purpose of faith. I'm not sure that you can do so without more mental gymnastics:, revision, etc
"You see that a person is considered righteous by what they do and not by faith alone." James 2:24
"For I tell you that unless your righteousness surpasses that of the Pharisees and the teachers of the law, you will certainly not enter the kingdom of heaven." Matt 5:20
"For if you forgive other people when they sin against you, your heavenly Father will also forgive you. But if you do not forgive others their sins, your Father will not forgive your sins." Matt 6:14-15
"If you want to enter life, keep the commandments.” Matt 19:17
“Woe to you, teachers of the law and Pharisees, you hypocrites! You clean the outside of the cup and dish, but inside they are full of greed and self-indulgence. Blind Pharisee! First clean the inside of the cup and dish, and then the outside also will be clean." Matt 23:25-26
"To those who by persistence in doing good seek glory, honor and immortality, He will give eternal life." R0m 2:7
"For it is not those who hear the law who are righteous in God’s sight, but it is those who obey the law who will be declared righteous." Rom 2:13
"But now that you have been set free from sin and have become slaves of God, the benefit you reap leads to holiness, and the result is eternal life. " Rom 6:22
"Therefore, brothers and sisters, we have an obligation—but it is not to the flesh, to live according to it. For if you live according to the flesh, you will die; but if by the Spirit you put to death the misdeeds of the body, you will live." Rom 8:12-13
"Make every effort to live in peace with everyone and to be holy; without holiness no one will see the Lord." Heb 12:14
"The acts of the flesh are obvious: sexual immorality, impurity and debauchery; idolatry and witchcraft; hatred, discord, jealousy, fits of rage, selfish ambition, dissensions, factions and envy; drunkenness, orgies, and the like. I warn you, as I did before, that those who live like this will not inherit the kingdom of God." Gal 5:19-21
"Do not be deceived: God cannot be mocked. A man reaps what he sows. Whoever sows to please their flesh, from the flesh will reap destruction; whoever sows to please the Spirit, from the Spirit will reap eternal life." Gal 5:7-8
"He said to me: “It is done. I am the Alpha and the Omega, the Beginning and the End. To the thirsty I will give water without cost from the spring of the water of life. Those who are victorious will inherit all this, and I will be their God and they will be my children. But the cowardly, the unbelieving, the vile, the murderers, the sexually immoral, those who practice magic arts, the idolaters and all liars—they will be consigned to the fiery lake of burning sulfur. This is the second death.” Rev 21:6-8
“Blessed are those who wash their robes, that they may have the right to the tree of life and may go through the gates into the city. Outside are the dogs, those who practice magic arts, the sexually immoral, the murderers, the idolaters and everyone who loves and practices falsehood." Rev 22:14-15
