He who began a good work in you will carry it on to completion until the day of Christ Jesus.
Philippians 2:3-4
Do nothing out of selfish ambition or vain conceit, but in humility consider others better than yourselves. Each of you should look not only to your own interests, but also to the interest of others.
Philippians 4:12
I know what it is to be in need, and I know what it is to have plenty. I have learned the secret of being content in any and every situation, whether well fed or hungry, whether living in plenty or in want.
