There is a difference between sinning and making a practice of sinning. Those who are God's people may stumble and sin, but our practice to repent and turn back to God. However, those who make a practice of sinning have neither seen him or known him (1 John 3:6). "Faith" is synonymous with "loyalty" and faith in God or loyalty to Him are both inherently moral works, so there is no distinction. Our loyalty to God should cause us to obey His commands. I'm not sure that I understand the significance or what you want me to remember about quoting from James.
The matter is not as simple as stated.
What is required of a loyal person? Loyalty. Loyalty is different for different people.
A king on a campaign to stamp out evil demands support from every group he encounters on his task. From one group rich in men and materials he demands volunteers and supplies. From another group consisting of old and poor men he requires only that they stop supporting evil practices. As long as any group does what it is capable of doing , it is safe from the wrath of the King.
Now what group do you and I fall into?
Are you in the group that can contribute, can fight?
No! A resounding no!
Romans 7:21I find then the principle that evil is present in me, the one who wants to do good. 22For I joyfully concur with the law of God in the inner man, 23but I see a different law in the members of my body, waging war against the law of my mind and making me a prisoner of the law of sin which is in my members. 24Wretched man that I am! Who will set me free from the body of this death?
Saddled with this body of death, we are a handicap in the fight against evil. If we try to join this campaign, we will be of no help. We will in fact be putting ourselves in harm's way:
Galatians 3:10For as many as are of the works of the Law are under a curse; for it is written, “CURSED IS EVERYONE WHO DOES NOT ABIDE BY ALL THINGS WRITTEN IN THE BOOK OF THE LAW, TO PERFORM THEM.” 11Now that no one is justified by the Law before God is evident; for, “THE RIGHTEOUS MAN SHALL LIVE BY FAITH.” 12However, the Law is not of faith; on the contrary, “HE WHO PRACTICES THEM SHALL LIVE BY THEM.”
That's a negative statement. What Paul says is that those who put themselves under the law shall die, because no one can meet the requirements of the law, and those who do not meet the requirements of the law will die. So why should a believer put himself in a harmful situation when there is a better option?
Which is to avoid being under God's wrath by being faithful, loyal. How can a person who is loyal but is saddled with a body of death show loyalty? By confessing!
Luke 18:14“I tell you, this man went to his house justified rather than the other; for everyone who exalts himself will be humbled, but he who humbles himself will be exalted.”
1 John 1:5This is the message we have heard from Him and announce to you, that God is Light, and in Him there is no darkness at all. 6If we say that we have fellowship with Him and yet walk in the darkness, we lie and do not practice the truth; 7but if we walk in the Light as He Himself is in the Light, we have fellowship with one another, and the blood of Jesus His Son cleanses us from all sin. 8If we say that we have no sin, we are deceiving ourselves and the truth is not in us. 9If we confess our sins, He is faithful and righteous to forgive us our sins and to cleanse us from all unrighteousness. 10If we say that we have not sinned, we make Him a liar and His word is not in us.
Does this mean that if we confess our sins and keep sinning we will be saved?
The point is that you will keep sinning whether you confess your sin or not. However, if we confess our sin, God tackles the root of the problem, our desires, rather than stop the results of that problem, our actions, the latter is which is what we try to do when we put ourselves under the law. And by the works that consist the following of the law no one can ever be justified because of our body of death.
Why would anyone want to put themselves under a useless scheme, that leads to no blessing, the blessing that comes automatically to those who have stopped from their own labour, because they are not slaves but sons, who do not work but inherit? What should those who are sons do? They should shed the last shreds of slavery that cling to them:
Galatians 3:But what does the Scripture say? “CAST OUT THE BONDWOMAN AND HER SON, FOR THE SON OF THE BONDWOMAN SHALL NOT BE AN HEIR WITH THE SON OF THE FREE WOMAN.”31So then, brethren, we are not children of a bondwoman, but of the free woman.
