G-d chose HIS people Israel with love.
This begs the question what is this love?
It is very simple G-d gave us the commandments. HE gave us a mission. HE gave us a task. We Jews have a special mission from G-d go out into the world to establish Holiness in the world.
This is real love.
G-d gave us the mitzvahs, the commandments to go out into the world to do and be G-d’s people and to establish G-d’s kingdom. This love G-d gave us is to be significant in this world.
