Blessed is the man who perseveres under trial, because when he has stood the test, he will receive the crown of life that God has promised to those who love him.
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 life not more important than 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.
Therefore do not worry about tomorrow, for tomorrow will worry about itself. Each day has enough trouble of its own.
Matthew 6:34 NIV
Cast your burden upon the Lord and He will sustain you: He will never allow the righteous to be shaken.
Psalm 55:22 NASB
God is our refuge and strength, a very present help in trouble.
He has made everything beautiful in its time. He has also set eternity in the hearts of men; yet they cannot fathom what God has done from beginning to end.
