The ultimate question !

[Psalm 23]

Is God omniscient? That means he knows everything, including what we do and think all of our lives - all of us. Then why ask Adam and Eve and Cain what they had done. Why send angels down to see if what the people were complaining about regarding Sodom and Gomorrah?

God knew Adam & Eve had sinned because they were hiding their nakedness. God wanted them to confess their sins. (That's where confession originates).. Just because God is omniscient, and he knows what we are going to do.. That doesn't mean he planned it that way. God gave us two options, "Right from Wrong." Did Eve know it was 'wrong' to eat from the Tree of Knowledge? Answer, yes! she knew it was wrong because God warned them, "Do not eat from this tree!" This is a story about Satan and how he will corrupt mankind into doing evil deeds. It still works that way to this day. Satan is speaking through pornography, heavy metal music, movies..etc,etc,etc.

Is God omnipotent? That means he can do anything, but then why does the Bible say he can't lie?

He chooses not to. Why would a perfect God lie? That would mean he's not perfect.

Is God omnipresent? That means he can be everywhere at once, but then why build a temple for him on Earth and why would the Bible say that his place is in heaven if his place was everywhere at once?

God commanded the Jews to build the Temple for a place of Worship. Heaven will be God's final eternal dwelling place.

It is a nonsensical way to justify the "mystery of God!" Bullshit. If you can't explain it just be honest about it, don't make it more difficult than it is for no other reason than to confuse would be my advise to those who take the 'omni's' seriously.

Everything was explained to you.

Edit: By the way, that isn't to say that God can't know anything he wants to know, or be anywhere he wants to be or do anything that he wants to do.

God can do as he wishes. That's why he was given the highest title known to man.
