12. Therefore I tell you, do not worry about your life, what you will eat and drink; or about your body, what you will wear. Is not life more important that food, and the body more important than clothes? Look 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? Who of you by worrying can add a single hour to his life?
Matthew 6:25-27

13. Ask and it will be given to you; seek and you will find; knock and the door will be opened to you. For everyone who asks receives; he who seeks finds; and to him who knocks, the door will be opened.
Matthew 7:7-8

14. Whoever finds his life will lose it, and whoever loses his life for my sake will find it.
Matthew 10:39

15. Come to me, all you who are weary and burdened, and I will give you rest. Take my yoke upon you and learn from me, for I am gentle and humble in heart, and you will find rest for your souls. For my yoke is easy and my burden is light.
Matthew 11:28-30
