God's goodness means that He is unchangeable

When it comes to what is God one aspect of divinity is the goodness of God. What do we mean by goodness? Of course, by it we do not mean to say God is good according to some standard outside of Himself otherwise He wouldn't be good. What we simply mean by the goodness of God is the perfection in which there is no shadow of turning, He does not change. God simply is a spirit and in Him he is not made of parts as the compound or complexity of humans.

John Gill speaks of the goodness of God in his Body of Divinity. He says, "The goodness of God is not distinct from his essence; for then he must be compounded of that, and his essence; which is contrary to his simplicity: he is good in and of himself, and by his own essence; and not by participation of another; for if he was not good of himself, and by his own essence, but of and by another; then there would be some being, both better than him, and prior to him; and so he would not be the eternal God, nor an independent Being, since he must depend on that from whence he receives his goodness; nor would he be the most perfect being, since what communicates goodness to him must be more perfect than he: all which, to say of God, is very unbecoming. It remains, then, that he is essentially good; is so in and of himself, by his own nature and essence." Pg. 92

With this we confess along with Jerome Zanchius,

"God is essentially unchangeable in Himself. Were He otherwise, He would be confessedly imperfect, since whoever changes must change either for better or for the worse; whatever alteration any being undergoes, that being must, ipso facto, either become more excellent than it was or lose some of the excellency which it had. But neither of these can be the case with the Deity: He cannot change for the better, for that would necessarily imply that He was not perfectly good before; He cannot change for the worse, for then He could not be perfectly good after that change. Ergo, God is unchangeable." pg. 25-26, Absolute Predestination

God is one and so His knowledge is eternal

"The knowledge of God proves him without successive duration. God knows all things, past, present, and to come, that is, which are so to us; not that they are so to him; these he knows at once, and all together, not one thing after another, as they successively come into being; all things are open and manifest to him at once and together, not only what are past and present, but he calls things that are not yet, as though they were; he sees and knows all in one view, in his all-comprehending mind: and as his knowledge is not successive, so not his duration." - John Gill, The Body of Divinity, Pg. 49

If there was a successive  moments in God, then He would not be immutable if he thought like us.

"Is not time measured by the succession of ideas in our minds?" says Philonous, in George Berkeley's Three Dialogues, Pg. 23

God, Eternity, Christ, Ascension

I do not see at all where the Second person of the Holy Trinity took upon himself flesh (as he is God). But, I do say that Christ (both God and Man) in the flesh ascended to the right hand of God the father.

1 Corinthians 15:20But now is Christ risen from the dead, and become the firstfruits of them that slept. 21For since by man came death, by man came also the resurrection of the dead. 22For as in Adam all die, even so in Christ shall all be made alive. 23But every man in his own order: Christ the firstfruits; afterward they that are Christ's at his coming. 24Then cometh the end, when he shall have delivered up the kingdom to God, even the Father; when he shall have put down all rule and all authority and power. 25For he must reign, till he hath put all enemies under his feet. 26The last enemy that shall be destroyed is death. 27For he hath put all things under his feet. But when he saith, all things are put under him, it is manifest that he is excepted, which did put all things under him. 28And when all things shall be subdued unto him, then shall the Son also himself be subject unto him that put all things under him, that God may be all in all.

Hebrews 2:17 - Wherefore in all things it behoved him to be made like unto his brethren, that he might be a merciful and faithful high priest in things pertaining to God, to make reconciliation for the sins of the people.

God's unchangeable covenant of grace

"God is unchangeable in his covenant of grace. This was made with Christ from everlasting, and stands fast with him; it is as immoveable as a rock, and can never be broken; the blessings of it are sure mercies, flow from the sovereign grace and mercy of God, and are sure and firm, being according to his unchangeable will, and are what he never repents of, nor revokes. . . . Rom. xi. 29. and viii. 30. the promises of the covenant, which are gone out of his mouth and lips are unalterable; what has been said of purposes may be said of promises, that they were made before the world were, by God, that cannot lie, who is all-wise, all-knowing, and all-powerful, and faithful to perform them." - John Gill, The Body of Divinity, Pg. 40

God's promises are never alterable. This is where assurance comes from. Even in the WCF Assurance is not grounded in our works but is grounded from the infallible promises of God. It is between God and Christ. It does not change. That is the gospel. Stay focus on who Jesus is. Justification is by faith alone. The Gospel assumes election. But, you can speak of all other points of doctrine and yet miss the gospel.

Negative and Positive statements of God's attributes

"The attributes of God are variously distinguished by divines; some distinguish them into negative and positive, or affirmative: the negative are such as remove from him whatever is imperfect in creatures; such are infinity, immutability, immortality, &c. which deny him to be finite, mutable, and mortal; and, indeed it is easier to say what God is not, than what he is: the positive, or affirmative, are such as assert some perfection in God, which is in and of himself; and which in the creatures, in any measure, is from him, as wisdom, goodness, justice, holiness, &c. but the distinction is discarded by others; because all negative attributes some positive excellency is found." -John Gill, The Body of Divinity, Pg. 34-35

For example, God is infinite which means he is timeless. Some Calvinist and Catholics teach that we can only speak of God in the negative statements. This makes no since. For one thing, if we can only speak of God in the negative only and not in any positive statements as well then how can we know him? I mean we know what he is not, but what is God as the WCF says.
