Given His Heart and His Nature, then God wants to realize or do something. In general, His Will is to create the world in which His Spirit and Heart can dwell, which reflects Him in all His fullness. In a word, the Kingdom of Heaven. Specifically, His Will is to create human beings who each fully reflect His Heart and nature. Now you necessarily start getting into history.
History means Providence.
Originally, God planned to send Adam and Eve immediately upon the full preparation of the universe, and that He promptly did. But Adam and Eve failed, and behaved as animals instead of responsible humans, and the Providence of Restoration developed. The goal of the Providence of Restoration is to prepare a chosen nation and on that foundation send the Messiah. God accomplished this, after many disappointments and setbacks, and sent Jesus Christ. But Jesus was rejected and crucified, purchasing spiritual salvation, but leaving this world under Satan's dominion.
