Life-Changing Verses

What life-changing truths are in these verses?

I rejoiced greatly in the Lord that at last, you renewed your concern for me.
Indeed, you were concerned, but you had no opportunity to show it.
I am not saying this because I am in need, for I have learned to be content whatever the circumstances.
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.
I can do all this through him who gives me strength. (Philippians 4:10-13, NIV)

1/ be grateful when people help you.
2/ be people who help others.
2/ be content when you have lots.
4/ be content when you have little.
5/ trust God for everything.

Prayer-Father God, please deepen our understanding of your word that we might serve you with more of you and less of us. Amen.
