Jesus Christ said,

"I tell you, do NOT worry about your life...
(Matthew 6:25).

Who of you by worrying can add a single hour to his life?...
(Matthew 6:27).

Therefore do NOT worry about tomorrow,
for tomorrow will worry about itself.
Each day has enough trouble of its own.
(Matthew 6:34).

Do NOT worry about anything,
but in everything, by prayer and petition,...present your requests to God.
(Philippians 4:6, NIV).
