What is the meaning of the biblical term "divine nature", and what does it tell us about the biblical use of the title "God"?

In connection with the term "God", mainstream Christology often uses the term “nature of God” or “divine nature”, especially when it comes to describing the triune God’s essence or substance, as it is found in Christ who is said to be the "God-man" in the hypostatic union , having both a fully human and a fully divine nature. Considering myself a human, I think to understand what is meant by "human" nature, as being part of the human species/lifeform. The term “divine nature” however seems quite abstract, and is found **only once** in the Bible, in **2 Peter 1:4** > by which have been given to us exceedingly great and precious > promises, that through these you may be partakers of the **divine > nature**, having escaped the corruption that is in the world through > lust. Re-born Christians have the “great and precious promise” of being “partakers of the divine nature”. The same Christians „shall be like Him (God)“ according to the Bible (1. John 3:2). One could conclude from this that Christians who become "partakers of the divine nature", fully inherit the "divine nature" when they go to heaven, and thus become fully God, if the term "God" is to be understood as a lifeform. On this point, I think most mainstream Christians would agree, that this is not the case - heavenly resurrected Christians don't become the "God" lifeform, but the "spirit" lifeform, as they receive a **spiritual body**. > It is sown a natural body, it is raised a **spiritual body**. There is a > natural body, and there is a **spiritual body**. > As was the man of dust, so also are those who are made of dust; and as > is the heavenly Man, so also are those who are heavenly. And as we > have borne the image of the man of dust, we shall also bear the image > of the heavenly Man. (1. Corinthians 15:44,48-49) Some Trinitarian Bible commentators agree: > **the Divine nature** may be understood of **the glory and immortality of > the other life**, wherein we shall be conformed to God, and whereof by > the promises we are made partakers. - Matthew Poole's commentary > **that by these you might be partakers of the divine nature;** not > essentially, or of the essence of God, so as to be deified, this is > impossible, for the nature, perfections, and glory of God, are > incommunicable to creatures; nor, hypostatically and personally, so as > the human nature of Christ, in union with the Son of God, is a > partaker of the divine nature in him; but by way of resemblance and > likeness, the new man or principle of grace, being formed in the heart > in regeneration, after the image of God, and bearing a likeness to the > image of his Son, and this is styled, Christ formed in the heart, into > which image and likeness the saints are more and more changed, from > glory to glory, through the application of the Gospel, and the > promises of it, by which they have such sights of Christ as do > transform them, and assimilate them to him; and which resemblance will > **be perfected hereafter, when they shall be entirely like him, and see > him as he is** - Gill's Exposition of the Entire Bible **“God is a spirit” (John 4:24)** A spirit is a (for humans) invisible supernatural lifeform. Thayer's Greek Lexicon describes the lifeform as: > 3. "a spirit, i. e. a simple essence, devoid of all or at least all grosser matter, and possessed of the power of knowing, desiring, > deciding, and acting"; Hence the question: the only time the Bible speaks of the "divine nature" it appears that from a biblical standpoint it means the lifeform of "incorruptible spiritual bodies". What other meaning can be drawn of the unique term "divine nature" from a biblical perspective? What is the biblical exegesis behind this term often used to describe God's essence? That the Almighty God is a unique person/being is out of the question, but is God a unique type of **lifeform** as appears to be the understanding and intermittent use of the term by people believing in the homoousion ? If so, what is the biblical basis for this claim? If not, what does the biblical term "God" really mean?
