You are commanded to do that. That’s the length of life. Then follow that: Love your neighbor as you love yourself. You are commanded to do that. That’s the breadth of life. And I’m going to take my seat now by letting you know that there’s a first and even greater commandment: “Love the Lord thy God with all thy heart, with all thy soul, with all thy strength.” I think the psychologist would just say with all thy personality. And when you do that, you’ve got the breadth of life.
And when you get all three of these together, you can walk and never get weary. You can look up and see the morning stars singing together, and the sons of God shouting for joy. When you get all of these working together in your very life, judgement will roll down like waters, and righteousness like a mighty stream.
