Psalm 37 verse 7-9
7 Rest in the LORD and wait patiently for Him; Do not fret because of him who prospers in his way, Because of the man who carries out wicked schemes. 8 Cease from anger and forsake wrath; Do not fret; it leads only to evildoing. 9 For evildoers will be cut off, But those who wait for the LORD, they will inherit the land.

Read Matthew 6 24-34
"No one can serve two masters; for either he will hate the one and love the other, or he will be devoted to one and despise the other. You cannot serve God and money.25"Therefore I tell you, do not worry about your life, as to what you will eat or what you will drink; nor for your body, as to what you will wear. Is life not more important than clothing? 26 "Look at the birds of the air, that they do not sow, nor reap nor gather into barns, and yet your heavenly Father feeds them. Are you not worth much more than they? 27 "And who of you by being worried can add a single hour to his life? 28 "And why do you worry about clothes? Observe how the lilies of the field grow; they do not labour nor do they spin, 29 yet I say to you that not even Solomon in all his glory clothed himself like one of these. 30 "But if God so clothes the grass of the field, which is alive today and tomorrow is thrown into the furnace, will He not much more clothe you? Oh you of little faith?! 31"Do not worry then, saying, `What will we eat?' or `What will we drink?' or `What will we wear for clothing?' 32"For the Pagans eagerly run after all these things; and your heavenly Father knows that you needs them. 33"But seek first His kingdom and His righteousness, and all these things will be added to you. 34"Therefore do not worry about tomorrow; for tomorrow will care for itself. Each day has enough trouble of its own.

A little about that..
You look at some animals, plants, how carefree do they seem? They don't have to worry about a thing, yet as it says above, we are so much more precious to God! We were created in His image! Therefore why do we worry? If God provides for the little birds, surely he will provide for us, since we are His most precious creation. All we need to do is that! Stop worrying! Say "God, I know You are there, knocking on the door, I don't wont to have to worry about things anymore, I want to follow You, and have You in my life, Lord I open the door, I allow You into my heart, and I will fully trust in You. You alone hold the key to the future, You know what I think, what i'm doing and what is going to happen, therefore I put all of my trust in You and turn my eyes from evil to follow You Lord."
