25"Therefore I tell you, do not worry about your life, what you will eat or drink; or about your body, what you will wear. Is not life more important than food, and the body more important than clothes? 26Look at the birds of the air; they do not sow or reap or store away in barns, and yet your heavenly Father feeds them. Are you not much more valuable than they? 27Who of you by worrying can add a single hour to his life? 28"And why do you worry about clothes? See how the lilies of the field grow. They do not labour or spin. 29Yet I tell you that not even Solomon in all his splendour was dressed like one of these. 30If that is how God clothes the grass of the field, which is here today and tomorrow is thrown into the fire, will he not much more clothe you, O you of little faith? 31So do not worry, saying, 'What shall we eat?' or 'What shall we drink?' or 'What shall we wear?' 32For the pagans run after all these things, and your heavenly Father knows that you need them. 33But seek first his kingdom and his righteousness, and all these things will be given to you as well. 34Therefore do not worry about tomorrow, for tomorrow will worry about itself. Each day has enough trouble of its own."
about being resentful
4 Even to your old age and grey hairs I am he, I am he who will sustain you. I have made you and I will carry you; I will sustain you and I will rescue you.
3 Commit to the LORD whatever you do, and your plans will succeed.
12I 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.
22Flee the evil desires of youth, and pursue righteousness, faith, love and peace, along with those who call on the Lord out of a pure heart. 23Don't have anything to do with foolish and stupid arguments, because you know they produce quarrels. 24And the Lord's servant must not quarrel; instead, he must be kind to everyone, able to teach, not resentful.
11 My son, do not despise the LORD's discipline and do not resent his rebuke, 12 because the LORD disciplines those he loves, as a father the son he delights in.
