When God created mankind He gave us a behavior mechanism of mind, wiolol, and emotion, just like the animals have only a bit more advanced. This behavior mechanism has to have a source of life to function (nobody sins after they die). The first human, Adam, had a spirit source of life, so his soul/behavior mechanism did not sin as fabricated. BUT God also gave man a free to choose will in his soul/behavior mechanism, so when Eve rebelled against God's command Adam was faced with a choice, to reject Eve or join her in a sate of rebellion. Adam chose to be with Eve and the life ibn his spirit departed, so that the only source of life for his soul was that of the flesh desires. Adam died that day, spiritually. and he passed thwt characteristic of a dead soul -alive in the carnal sense only- onto all descended from him.
We are born with a body, a soul/behavior mechanism, and a spirit, a spirit that is not alive spiritually so it cannot give lief to the soul. BUT GOD has made provision to renew the life to the spirit, in Christ and what He accomplished on the cross. While bod yet lives it is drawing carnal life from the flesh for the soul. (No one sins after thay die) When one is born again, God separated the soul and sp[irit so thaty He puts His spirit life into the spirit, but separate fromt he soul so the soul still accomplishes sin. (See Heb 4:12, for separation of soul and spirit).
Someday God has Promised to give the born agains a new glorified body and soul, for the spirit wherein He abides (See John 3:9) to live forever more, sinless. Honestly, I am awaiting that day, groaning in anticipation.
And if god did not create mankind then what is the reason for the state of humanity as described by the author..???
ABSOLUTE GIBBERISH! No matter how you spew your garbage, Sin is the transgression of God's law. And all who commit willful and unrepentant sin, INCLUDING born again Christians, will never enter heaven. God does not make us robots at the moment of Grace. We are responsible for our actions/sin. God will not tolerate willful and unrepentant LAWLESSNESS. Hebrews 4:12 has absolutely nothing to do with the "spirit" preventing the wages of willful and unrepentant sin. All those years of study and listening to your false teachers, and you still don't get it.
Hewbrews 4:12 Soul and spirit. Gr. psuchē kai pneuma, here, “life and breath.” On psuchē see on Matt. 10:28, and on pneuma see on Luke 8:55. This and the expression “joints and marrow” are used figuratively. The idea of dividing between “soul and spirit” and between “joints and marrow” describes the sharpness of God’s “word.” The value of the figure is based on the idea that “life” and “breath” are, for practical purposes at least, inseparable. SDA Bible Commentary
Matthew 10:28 Soul. Gr. psuchē, “breath,” “life,” or “soul.” Psuchē (plural, psuchai) is translated 40 times in the NT as “life” or “lives,” clearly with the meaning commonly attributed to the word “life” (see chs. 2:20; 6:25; 16:25; etc.). It is rendered 58 times as “soul” or “souls” (see chs. 10:28; 11:29; 12:18; etc.). In some of these instances it means simply “people” (see Acts 7:14; 27:37; 1 Peter 3:20; etc.). In other instances it is translated as, or equivalent to, some personal pronoun (see Matt. 12:18; 2 Cor. 12:15; see on Ps. 16:10). At times it refers to the emotions (see Mark 14:34; Luke 2:35; etc.), to the natural appetites (see Rev. 18:14), to the mind (see Acts 14:2; Phil. 1:27), or to the heart (see Eph. 6:6). There is nothing in the word psuchē itself that even remotely implies a conscious entity that is able to survive the death of the body and hence be immortal. In no instance of its use in the Bible does psuchē refer to a conscious entity able to exist apart from the body. The Bible knows nothing of a living, conscious soul that, supposedly, survives the body. For the Heb. nephesh, the Hebrew equivalent of the Gr. puschē, see on 1 Kings 17:21; Ps. 16:10. All that is said of one word applies to the other. SDA Bible Commentary
Luke 8:55 55. Spirit. Gr. pneuma, ―wind,‖ ―breath,‖ or ―spirit,‖ from pneō, ―to blow,‖ or ―to breathe.‖ Any extension of the word to designate beings possessed of intelligence is a figure of speech known as synechdoche, by which a thing is referred to by naming one of its parts, usually that part which is most characteristic of it. There is nothing inherent in the word pneuma by which it may be taken to mean some supposed conscious entity of man capable of existing apart from the body, nor does the usage of the word with respect to man in the NT in any way imply such a concept. This concept is based exclusively on the preconceived opinions of those who, a priori, believe that a conscious entity survives the body at death, and who read this preconceived opinion into such words as ―spirit‖ and ―soul.‖ For the OT equivalent of pneuma, the Heb. ruach, see on Num. 5:14 SDA Bible Commentary
