Romans 12:16
Have full sympathy with one another. Do not give your mind to high things, but let humble ways content you. Do not be wise in your own conceits.
Matthew 6:25-32
For this reason I charge you not to be over-anxious about your lives, inquiring what you are to eat or what you are to drink, nor yet about your bodies, inquiring what clothes you are to put on. Is not the life more precious than its food, and the body than its clothing?
1 Corinthians 7:26-32
I think then that, taking into consideration the distress which is now upon us, it is well for a man to remain as he is.
1 Timothy 6:6-9
And godliness *is* gain, when associated with contentment;
Hebrews 13:5
Your lives should be untainted by love for money. Be content with what you have; for God Himself has said, "I will never, never let go your hand: I will never never forsake you."
