Matthew 6:25-34 NIV
“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 than food, and the body more than clothes? [26] 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? [27] Can any one of you by worrying add a single hour to your life ? [28] “And why do you worry about clothes? See how the flowers of the field grow. They do not labor or spin. [29] Yet I tell you that not even Solomon in all his splendor was dressed like one of these. [30] If 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---you of little faith? [31] So do not worry, saying, 'What shall we eat?' or 'What shall we drink?' or 'What shall we wear?' [32] For the pagans run after all these things, and your heavenly Father knows that you need them. [33] But seek first his kingdom and his righteousness, and all these things will be given to you as well. [34] Therefore do not worry about tomorrow, for tomorrow will worry about itself. Each day has enough trouble of its own.

Philippians 4:6-7 NIV
Do not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, present your requests to God. [7] And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus.

Hebrews 11:1 KJV
Now faith is the substance of things hoped for, the evidence of things not seen.

Romans 10:17 KJV
So then faith cometh by hearing, and hearing by the word of God.

Proverbs 4:5-10 KJV
Get wisdom, get understanding: forget it not; neither decline from the words of my mouth. [6] Forsake her not, and she shall preserve thee: love her, and she shall keep thee. [7] Wisdom is the principal thing; therefore get wisdom: and with all thy getting get understanding. [8] Exalt her, and she shall promote thee: she shall bring thee to honour, when thou dost embrace her. [9] She shall give to thine head an ornament of grace: a crown of glory shall she deliver to thee. [10] Hear, O my son, and receive my sayings; and the years of thy life shall be many.
