The triune God before time itself decided to create a universe as an overflow of the love they had always enjoyed. In a battle between inaction and love - Love wins
The people God created turn their back on him and start making something of a mess of the universe he created. However, God continues to be long suffering, patient and kind with them as he reveals himself to them and works to restrain evil and bring people back into relationship with him. In a battle between indifference and love - Love wins
Knowing full well mankind's inability to relate to him, each other or creation properly, God the Son becomes a man and suffers incredible hardship and difficulty as eventually he is crucified by the very people he came to rescue. Through this crucifixion forgiveness is made possible and through this a renewed relationship of love between people and God. In a battle between comfort and love - Love wins
One day God promises a new creation in which everybody relates to each other, and to God, in perfect love. God will not allow hate, suffering, and all kinds of evil to go unchecked and one day he will do away with them forever. Ultimately in the battle between sin and love - Love wins
So about this much at least Rob Bell is right - Love definitely wins!
