Two words: Theological Evolution. Look up Open Theism, it’s a Christian doctrine that attempts to understand God as he is portayed in the Scriptures, not as he is portayed historically by the Church.
The earliest parts of the Bible do say that Yahweh is strong, Yahweh says to Abraham, “Is anything too difficult for Yahweh?” (side note: this is one of the many verses in the Hebrew Scriptures that seem to imply that there exist two powers in heaven named Yahweh, as Yahweh should say, “Is anything too difficult for me?”)
But, later we see that while Yahweh certainly has a vast array of powers but some things certainly are too difficult for Yahweh.
Judges 1:19, “And [Yahweh] was with Judah; and he drave out the inhabitants of the mountain; but could not drive out the inhabitants of the valley, because they had chariots of iron.”
God did not know all things, he certainly had an affinity for telling the future but he certainly did not know all.
Genesis 18:20-21, “20 And the [Yahweh] said, ‘The outcry of Sodom and Gomorrah is indeed great, and their sin is exceedingly grave. 21 I will go down now, and see if they have done entirely according to its outcry, which has come to Me; and if not, I will know.’”
Why would Yahweh need to go and see if the prayers people are telling to him are true or not? If he knows all, shouldn’t he know this?
And Yahweh even controlled people against their will and if the Christian Church is right about hell, damned them himself.
Exodus 11:10, “10 Moses and Aaron performed all these wonders before Pharaoh; yet [Yahweh] hardened Pharaoh’s heart, and he did not let the sons of Israel go out of his land.”
Deuteronomy 2:30, “30 But Sihon king of Heshbon was not willing for us to pass through his land; for [Yahweh] your [Eloheim] hardened his spirit and made his heart obstinate, in order to deliver him into your hand, as he is today.”
1 Samuel 16:14, “14 Now the Spirit of [Yahweh] departed from Saul, and an evil spirit from [Yahweh] terrorized him.”
And my personal favorite:
1 Kings 22:19-23, “19 Micaiah said, ‘Therefore, hear the word of [Yahweh]. I saw [Yahweh] sitting on His throne, and all the host of heaven standing by Him on His right and on His left. 20 [Yahweh] said, “Who will entice Ahab to go up and fall at Ramoth-gilead?” And one said this while another said that. 21 Then a spirit came forward and stood before [Yahweh] and said, “I will entice him.” 22 [Yahweh] said to him, “How?” And he said, “I will go out and be a deceiving spirit in the mouth of all his prophets.” Then He said, “You are to entice him and also prevail. Go and do so.” 23 Now therefore, behold, [Yahweh] has put a deceiving spirit in the mouth of all these your prophets; and [Yahweh] has proclaimed disaster against you.’”
I honestly recommend everyone to read 1 Kings 22 It’s really funny.
But, there were certainly other gods. That Israel worshipped such as Baal, Asherah, El, and others. But, because of Israel’s marriage covenant with Yahweh, these relationships with other gods were certainly worthy of Yahweh’s jealous rage.
Later, during the Babylonian Exile, Judaism was syncretized with Zoroastrianism. And Yahweh lost his negative traits. And the other gods lost their existence, as Zoroastrianism was monotheistic and now so was Judaism.
Christianity is the result of the syncretism between Judaism and Zoroastrianism, there are many things Jesus says that implies that he’s a Pharisee, and the Pharisees were descendants of the Farsis, who are adherents of Zoroastrian, indeed it is the Pharisees that have evolved into modern day Rabbinic Judaism.
As time passed, the Church began to view the Hebrew Yahweh through a Greek lens, even going so far as to say that within the writings of Plato, Socrates, and Aristotle lay the “seeds of the gospel”
And so, it is through this syncretic union between Hebrew and Greek thought by the early Fathers of the Church, that we came up with ideas such as omniscient, omnipotent, omnipresent, omnibenevolent, etc., etc.
