Because God is the strongest and loves all out of charity, there's no strong, good, or beautiful. There's only God.
God calls you to love everyone for their own sake, not because you admire or want something from that person. This is the virtue of charity.
liking/disliking, has nothing to do with love, which is an act of the will (to will the good of the other). I love a lot of people that I dislike.
Consider how insignificant you are compared to God, yet He still loves you, not because of your qualities or because He gets something from this love. You sin against God day and night, yet he patiently waits so you have a chance to convert.
I recommend reading the story of st Christopher.
