Well, let me say it this way: Would you offer me some grace on the topic?
We can not say anything about God outside of HIS written word. Where the Word of God is Silent on a topic, we should also remain silent. Because Truth should be our only Motivation when speaking of the Living God.
To say "God can't" and not show it biblically is an error. God can not Lie.
Titus 1:2 and Hebrews 6:18
God can not sin. James 1:13
I would agree from what I see in the word of God for God not to exist or in the future is unbiblical Because HE is the Eternal God.
Psalm 90:2, Isaiah 41:4, and Romans 1:20
I would not need to speak about absurdities when the Word of God has already.
Sure, here is my grace (which I credit to God):
God’s
omnipotence means that He can do everything except “disown Himself” or not be God (2TM 2:13). It does NOT mean that God can perform logical absurdities, such as creating a rock too large for Him to move. Omnipotence or sovereignty also means that human MFW has limits with regard to how it can contradict God’s will. God provides morally competent humans the ability to resist His intentional will and plan of salvation (POS) within limits, such as the time limit that will end with death, resurrection (the last miracle) and judgment (per HB 9:27)–called His permissive will.
Divine
omniscience includes knowledge of people’s thoughts (PS 94:11, MT 12:25) and the foreknowledge of events (ACTS 2:23, RM 8:29, 11:2, 1PT 1:2). Some people think that God even knows what a person will be/do before that person exists (JR 1:5). If this view is correct, it must be maintained that God’s foreknowledge does not predetermine a person’s spiritual choice regarding the satisfaction of God’s requirement for salvation or else moral responsibility would be abrogated, which contradicts Scripture teaching that sinners are accountable and damnable. (I find it simpler to think that God merely tweaks the river of history occasionally to keep if flowing in the direction He intends but allows the fish to swim as they wish.)
When GW does not address a topic, we must use our God-given gift of logic, praying that we are guided by the
Spirit of Truth. (I believe every normal adult has some reasoning ability, hopefully at least the amount called common sense.)
To say both God can and cannot do something is problematic without Scriptural support, and I am glad you finally agree that Scripture does not support saying that God can do the absurd.
Biblical passages that seem to support the view that human logic is a divine gift include the following:
1. “Come now, let us reason together,” says the Lord. (IS 1:18a)
2. “They hated me without reason.” (JN 15:25)
3. “So [Paul] reasoned in the synagogue with the Jews and the God-fearing Greeks, as well as in the marketplace day by day with those who happened to be there.” (ACTS 17:17)
4. “We do, however, speak a message of wisdom [right reasoning] among the mature…” (1CR 2:6)
5. “When I was a child… I reasoned like a child. When I became a man, I put childish ways behind me.” (1CR 13:11)
6. “Always be prepared to give an answer to everyone who asks you to give the reason for the hope that you have.” (1PT 3:15b)
