God made all His creation out of pure love. God doesn’t depend on anything or anyone in order to be perfectly happy. He simply wanted to make a creation to enjoy this omniscient bliss, too.
The crowns of His creation are human beings who are ‘created gods’. However, humanity threw away this perfection, bringing down the entire created world into a distorted state.
God then became human in order to save His creation, even going so far as to die Himself, inasmuch as this is possible for the immortal God. This was (and is) the greatest anomaly ever: our immortal and perfect God, the Creator, was murdered by the beings He had created and destined to be like Him.
