Why do we love? Because God first loved us. He loves us so much that he sent his son to die for our sins. Jesus said that the greatest commandment was to love the Lord your God with all your heart, your soul, your mind and your strength. He then followed that up with love your your neighbor as yourself. Jesus loves us enough to die for us, even though some us may never actually accept his sacrifice. He even died for you while you were still his enemy. If Jesus is willing to show that kind of love don’t you think you should be willing to love others in the same manner and at the very least love Jesus back.
