If Aum/OM (an image) is ultimate GOD, should I throw away Kali, Durga, Vishnu, Shiv, etc.?

I got answer here, that Aum/OM is ultimate true GOD then I must remove Kali Durga Vishnu Shiva, Hanuman etc. from my house/mind. I want to worship only ALMIGHTY FATHER GOD, who is creater, destroyer, provider and GOD of every microsecond for eternal. In "Upanishada" and "Geeta" it is written that all devi/devtas are mortal and only GOD "PARAMATMA" (FATHER) provides them strength then why should I go blind after wrong images and idols. Should I throw them away to attain MOKSH or FATHER.
