Well, if you found someone that has an image of a god in their head, that wouldn't be God. God cursed the children of Israel for building a golden calf, and that was almost immediately after He told them, "Thou shalt not make for yourselves any graven images, of anything in the sky, or on the earth, or in the seas, or under the earth."
But to those who DO have a false image of God, I must warn you what Paul said to the Romans:
Romans 1:
18 But God shows his anger from heaven against all sinful, wicked people who suppress the truth by their wickedness. 19 They know the truth about God because he has made it obvious to them. 20 For ever since the world was created, people have seen the earth and sky. Through everything God made, they can clearly see his invisible qualitiesâ€â€his eternal power and divine nature. So they have no excuse for not knowing God.
21 Yes, they knew God, but they wouldn’t worship him as God or even give him thanks. And they began to think up foolish ideas of what God was like. As a result, their minds became dark and confused. 22 Claiming to be wise, they instead became utter fools. 23 And instead of worshiping the glorious, ever-living God, they worshiped idols made to look like mere people and birds and animals and reptiles.
24 So God abandoned them to do whatever shameful things their hearts desired. As a result, they did vile and degrading things with each other’s bodies. 25 They traded the truth about God for a lie. So they worshiped and served the things God created instead of the Creator himself, who is worthy of eternal praise! Amen. 26 That is why God abandoned them to their shameful desires. Even the women turned against the natural way to have sex and instead indulged in sex with each other. 27 And the men, instead of having normal sexual relations with women, burned with lust for each other. Men did shameful things with other men, and as a result of this sin, they suffered within themselves the penalty they deserved.
28 Since they thought it foolish to acknowledge God, he abandoned them to their foolish thinking and let them do things that should never be done. 29 Their lives became full of every kind of wickedness, sin, greed, hate, envy, murder, quarreling, deception, malicious behavior, and gossip. 30 They are backstabbers, haters of God, insolent, proud, and boastful. They invent new ways of sinning, and they disobey their parents. 31 They refuse to understand, break their promises, are heartless, and have no mercy. 32 They know God’s justice requires that those who do these things deserve to die, yet they do them anyway. Worse yet, they encourage others to do them, too.
God curses them with homosexuality if they worship images " idols made to look like mere people and birds and animals and reptiles."
