3 Do nothing out of selfish ambition or vain conceit. Rather, in humility value others above yourselves, 4 not looking to your own interests but each of you to the interests of the others. 5 In your relationships with one another, have the same mindset as Christ Jesus:
Forgive me Lord. When I approach a situation (e.g., buying a donut at the donut shop) I often approach it with the focus on completing the task (correctly, Type-A tendency). According to the Bible, this is the incorrect way to approach the situation. I should be first valuing others and looking to fulfill the interests of them. Lord, help me to remember this and put it into practice. Help me to become a person that does this.
The insight of the passage: (1) Notice how it begins. It begins squarely with our selfish ambition (which is our animal tendency). (2) Notice that it refers to everything. If it would have said, look after the interests of others and value others, it would imply these are good things to do from time to time (like mowing the yard, eating, taking a shower, taking a hike), but not something to consider all the time.
