The question is not whether Paul has a proper understanding of those things, but rather, do we understand Paul? Paul, who was Saul, no doubt knows of what he speaks. So according to the context you must first do the will of Elohim. For if not then how can you understand if you are not doing what you know is the will of Elohim? Only those who do His will can even begin to understand; for if not, then you cannot receive the Promise. So what then is the will of Elohim? Yeshua expounds the will of Elohim in all his parables, allegories, idioms, sayings, and doctrine.
1 Thessalonians 4:1-8 KJV
1 Furthermore then we beseech you, brethren, and exhort you by the Lord Jesus, that as ye have received of us how ye ought to walk and to please God, so ye would abound more and more.
2 For ye know what commandments we gave you by the Lord Jesus.
3 For this is the will of God, even your sanctification, that ye should abstain from fornication:
4 That every one of you should know how to possess his vessel in sanctification and honour;
5 Not in the lust of concupiscence, even as the Gentiles which know not God:
6 That no man go beyond and defraud his brother in any matter: because that the Lord is the avenger of all such, as we also have forewarned you and testified.
7 For God hath not called us unto uncleanness, but unto holiness.
8 He therefore that despiseth, despiseth not man, but God, who hath also given unto us his holy Spirit.
Paul clearly tells us that he preaches the commandments of Messiah, and that the will of Elohim, if we do it, even concerns our own sanctification. And these things concern cutting off sin from our own "members", that is, to "mortify the deeds of the body", and to "mortify your members which are upon the land", every man has his land with its house-body-temple and its "fields" roundabout. The fields gain tares along the way which are bundled for burning and cast into the fire at the end of your age in the summer of your harvest, (no man knows the day, but the Father only). And when the Master comes will he find faithfulness in your land? The man is the Land, both the adamah-soil of the heart, (Parable of the Sower), and the erets-land outer bounds "commons-profane" outer boundaries of the temple, ("the flesh"). So then, with the mind I serve Torah of Elohim, (Horeb of above), but with the flesh the Torah of sin and death, (Sinai of below), and cut off the evil doers from the Land which the Father has given me to shepherd while the House Master is away in a far journey, (Mark 13:34-37). But if an evil shepherd be allowed to rise up in your dominion, and shall begin to smite the fellow members and house servants of your household, and to eat and drink with the drunken; beware, for the Master shall come in a day when he looks not for him, and in an hour that he is not aware of, and shall cut him in half, and he will appoint the hypocrite his portion with the hypocrites: there shall be weeping and gnashing of teeth.
Hebrews 10:35-39 KJV
35 Cast not away therefore your confidence, which hath great recompence of reward.
36 For ye have need of patience, that, after ye have done the will of God, ye might receive the promise.
37 For yet a little while, and he that shall come will come, and will not tarry.
38 Now the just shall live by faith: but if any man draw back, my soul shall have no pleasure in him.
39 But we are not of them who draw back unto perdition; but of them that believe to the saving of the soul.
And this is the will of Elohim, even your sanctification, for you are bought with a price and are not your own:
Mark 9:42-49 KJV
42 And whosoever shall offend one of these little ones that believe in me, it is better for him that a millstone were hanged about his neck, and he were cast into the sea.
43 And if thy hand offend thee, cut it off: it is better for thee to enter into life maimed, than having two hands to go into hell, into the fire that never shall be quenched:
44 Where their worm dieth not, and the fire is not quenched.
45 And if thy foot offend thee, cut it off: it is better for thee to enter halt into life, than having two feet to be cast into hell, into the fire that never shall be quenched:
46 Where their worm dieth not, and the fire is not quenched.
47 And if thine eye offend thee, pluck it out: it is better for thee to enter into the kingdom of God with one eye, than having two eyes to be cast into hell fire:
48 Where their worm dieth not, and the fire is not quenched.
49 For every one shall be salted with fire, and every sacrifice shall be salted with salt.
And as for the "little ones" of which he speaks, Take heed that you despise not one of these little ones; for I say unto you, that in heaven their angels do always behold the face of the Father which is in the heavens: for the Son of man is come to save that which was lost, and the Absolute Master is the Avenger of all such, as we also have forewarned you and testified. Three evil shepherds I cut off in one year: an evil wandering right eye always wandering off toward unsightly things like a desert nomad wandering goat; an evil right hand master of wicked works; an evil foot always running swiftly into mischief; and and my soul loathed them, and their soul also abhorred me. Then said I, I will not feed you: that that which is dying, let die; and that that is to be cut off, let it be cut off; and let the rest eat every one the flesh of his neighbor. And the Word said to me, Take yet unto yourself the instruments of a foolish shepherd, for behold, I raise up a shepherd in the land, which shall not visit those that be cut off, neither shall seek the young, nor heal what is broken, nor feed what is sound: but he shall eat the flesh of the fat, and tear their claws in pieces. Woe to the idol shepherd that abandons the flock! The sword shall be upon his arm, and upon his right eye: his arm shall be clean dried up, and his right eye shall be utterly darkened! And the lamp to light of the inside of the body of the man is the eye: if therefore your eye be single, your whole body shall be full of light; but if your eye be evil, your whole body shall be full of darkness; if therefore the light that is in you be darkness, how great is the darkness! So you see, it is not "all eyes" that will see the Holy One coming with the clouds of heaven, but rather, "every eye". Therefore one must get to doing the will of Elohim: Pluck, pluck! Chop, chop!
And those "members" of your household which you have been forced to put to sleep will arise in the last day, otherwise why immerse for the dead if they rise not? We wash them in the washing of water into the Word. And when they rise you will not precede them; for the dead in Messiah rise first. Blessed are the dead who die in the Master from henceforth, yea, the Spirit says, that they may rest from their labors; and their works do follow with them. Therefore, I say, it is ridiculous to think that false doctrines have a consciousness, (ECT), they do not have awareness but simply enter into a man and kill whosoever eats them and spews them out for others to consume. They must therefore go into the fire at the end of your age. All things are done in parables.
