Revelation 1:8 - I am Alpha and Omega, the beginning and the ending, saith the Lord, which is, and which was, and which is to come, the Almighty.
Almighty according to the Lexicons:
G3841
παντοκράτωρ
pantokratōr
pan-tok-rat'-ore
From G3956 and G2904; the all ruling, that is, God (as absolute and universal sovereign): - Almighty, Omnipotent.
According to the book you read called the "bible", God is Omnipotent, this is not MY opinion, this is what your book that you read says. You have yet to prove me wrong, I am simply using the bible, showing the definition of the word as it means in the original language. If you can somehow disprove this then great! Philosophical interpretations and personal opinions is just that, look at the source.
