From Jesus Calling:
Do not worry about tomorrow! This is not a suggestion, but a command. My grace is sufficient for you but for only one day at a time. Throw off the oppressive burden of worry with a quick thrust of trust. Enjoy my presence by continually trusting me at all times.
Therefore do not worry about tomorrow, for tomorrow will worry about itself. Each day has enough trouble of its own. Matthew 6:34
Worrying is like paying interest on a loan that never comes due. Help me Lord not to worry about tomorrow as I put all of my trust in you, Amen.
