God's sovereignty is who HE Is. There is nothing MORE to it.
Omnipotent, Omniscient, Omnipresent, Immutable......these encompass His love, wrath and will.
If God is not all powerful, knows all and is ever present and changes never, then who do you say He is?
Everything God has done IN LOVE, He has done for HIS PEOPLE. A select group called the elect, people He chose who had absolutely NO merit so no one would boast.......and gave them the gift.
To be sovereign in modern culture usually means a leader who rules over a fraction of the world and actually is more a figure-head than a TRUE sovereign. Sovereign, in that sense, is title of respect and has nothing to do with power.
God is love? Some sappy, snowflake idea of a great big Santa in the sky? Yet that "god of love" is not biblical. God loves HIS people, but does not love everyone. Even those He loves He scourges. We are not here to be "loved", we are here to be holy (set apart) for God's purpose.
