All the reasons why you should not worry:
1. God.

1 Peter 1:7 ... Casting all your care upon him; for he careth for you.
Matthew 6:34 ... Take therefore no thought for the morrow: for the morrow shall take thought for the things of itself. Sufficient unto the day is the evil thereof.
Philippians 4:6 ... Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God. ❤
