1. Have real goodwill toward the other person
2. Put the other person first
3. Be eager in meeting the needs of others, not begrudging and reluctant
4. Be proactive, not reactive, in doing good
5. Avoid a self-protective mindset and take pains to do good for others
6. Be creative and competent in doing good, not lazy and shoddy

Matt Perman writes that loving others boils down to one thing:

How would I want someone else to treat me? And then the gospel amps it up: How did Christ treat me? Go do that.
