Because God is the power in us that knows what is good, Love by virtue of being created by God. It is unrighteous to think otherwise. Do unto others as we would have done unto us is self-evident, and so to do unto others what we would not want done to us is incriminating and hypocritical. Love does the golden rule by force of empathy not by the ability to reason.
That's what I just said. I would only add that Paul is most likely refering generally to all men.
That's what I just said. It is the power of God the Godhead that reveals what is good not freewill. It is unrighteous to claim that men have the power to be good without Love. Hence those who believe this, hold the Truth in unrighteousness. Pharisees deceived in self righteous vanity that is Satanic in nature.
As I said above
I see Paul refering to the unrighteousness that supresses the Truth as further being described as not esteeming God as God when they knew God, hence he mentions the Godhead through which knowledge of all things Godly comes as God's attributes given to men and not our own attributes.
The just deserts for such ignorance is that men were given over to the lusts of the flesh whereas had they acknowledged that God is the wisdom in them and not themselves, there would have been no vanity. But instead being unthankful and thinking they were wise they became fools. So it is we all experience lust because we had the same vanity that was introduced by Satan and his angels and this is evident wherein Satan says we can disobey God and yet live. And Satan proposes that through the knowledge of good and evil we could be like God which presupposes that God chooses to be good or evil through such knowledge rather than He is good because He is the Spirit of goodness. And this is the form of freewill I oppose. But do not oppose the freewill that says we have no excuse for vanity. For we already had a freewill without this knowledge of good and evil in the form of Love. That is why there are semantics involved with this topic. We tried to fix what was not broken and broke it.
And this is made more clear through the fact we all have been made subject to lust of the flesh. And so this is not by our freewill that we lust but rather an enslaved will. For that is why Paul says in Romans two,"therefore you are inexcusable whoever you are who judges another for wherein you judge another you condemn yourself". And elsewhere he reiterates saying "that which I will to do, I do not; but that which I will not to do , that I do".
So in conclusion if we admit we wrongly took God for granted and this is why there is sin through lust of the flesh, we cannot now be double minded and hold others accountable for their sin through such lust lest we condemn ourselves. But God can, since He it was who was our goodness, whom we took for granted in the first place when we did not esteem God as God, which is why it is by mercy we are saved.
Ephesians 2:2-3
King James Version (KJV)
2Wherein in time past ye walked according to the course of this world, according to the prince of the power of the air, the spirit that now worketh in the children of disobedience: 3Among whom also we all had our conversation in times past in the lusts of our flesh, fulfilling the desires of the flesh and of the mind; and were by nature the children of wrath, even as others.
I see a lot of words with barely a whisper of knowledge in them. It's a mixed up world, but it isn't that mixed up.
Rather than waste your "love" by telling me how unrighteous I am for understanding the Word as it's plainly written, perhaps you should concentrate on searching the Scripture to find our how love is shown forth in the believer.
