I fully agree. The New Testament is an upgrade. So, it is not only our actions that we need to keep in check, but also our thoughts.
You mentioned faith without works is dead. This comes from James 2:14-17. I believe that many people miss the meaning of these verses.
I do think that we are to feed the hungry and clothe the poor. This is mentioned in other areas of the bible. And to leave someone hungry is not loving your brother.
But
James 2:14-26 does not say that we lead with good deeds. It is saying that if we truly have a faith, then we will act in accordance with that faith. Faith without works is dead. So, if we believe that there is a God and that he will judge everyone, then we will act in accordance with that belief. We would warn people of it. It would be unloving not to.
Just as when you see a person without clothes, you believe that they will freeze, and so you clothe them. You acted according to what you believed. It would be unloving not to.
James 2:14-17 says "
What good is it, my brothers and sisters, if someone claims to have faith but has no deeds? Can such faith save them? Suppose a brother or a sister is without clothes and daily food. If one of you says to them, “Go in peace; keep warm and well fed,” but does nothing about their physical needs, what good is it? In the same way, faith by itself, if it is not accompanied by action, is dead."
Notice verse 17, uses the words, "In the same way". This means in a "
likewise manner" or "similar" but not the exactly same.
So,
likewise, if you saw a house on fire, you would yell and warn the people inside. You believe that the house is on fire and that the person will die if you do not urgently warn them.
And again.
Likewise, in the same way, you if we see a non-believing brother or sister under God's wrath, and we say to them, “Be our friend”, but do nothing to warn them of their condemnation, what good is that? Faith without works is dead.
Yes, we will feed the hungry and clothe the poor. It would be unloving not to, but even unbelievers will do the same. They also believe that those who do not have clothes should be warm.
But an unbeliever will not tell others of His great sacrifice. They don’t tell of Him because they do not have faith in Him. If we have faith, then we will act in accordance with that faith. Faith without works is dead. So, tell others about the great condemnation that they are under and tell them of the Great sacrifice He made for us.
So, yes, feed the hungry and clothe the poor. This shows that you love and care for them.
I do not think that the Law of Liberty is made up. It is simply to honour God by leaving your sin. This will encompass the commandments that Jesus expanded. The Law of Liberty is mentioned in James 1:25 but prior to this it says "
Therefore, ridding yourselves of all filthiness and all that remains of wickedness, in humility receive the word implanted, which is able to save your souls. But prove yourselves doers of the word, and not just hearers who deceive themselves." So, obey God. Choose to honour Him. It would be wrong to look into the mirror of the ten commandments and then to walk away thinking you are a good person.
So, when we are born again, God will give us a new heart. One that loves righteousness and hates evil. With this new heart, we will have a battle within us. A battle of the Spirit versus the Flesh. And this is a hard battle. Not an easy one. It is a war. But we need to let the Spirit overflow and fill us.
