We are all born, without exception, selfish in the core of our beings. This self-focus is entrenched in our sinful nature, and though there are compassionate people in society, the general human tendency is not to be focused on the well-being of other people.
Compassion is the focus of God. "For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life" (John 3:16, NIV). In the same way, as God's children, we are to be more concerned about other people than ourselves. We are to love and serve others—God's entire ministry to us is about others.
And to "love and serve others" doesn't mean just our friends! Jesus was clear when He said, "You have heard that it was said, 'Love your neighbor and hate your enemy.' But I tell you, love your enemies and pray for those who persecute you, that you may be children of your Father in heaven."
