George MacDonald, the nineteenth-century British preacher and author, said, "It is not the cares of today, but the cares of tomorrow, that weigh a man down. For the needs of today we have corresponding strength given. For the morrow we are told to trust. It is not ours yet. It is when tomorrow's burden is added to the burden of today that the weight is more than a man can bear.

Don't worry about anything; instead, pray about everything. Tell God what you need, and thank him for all he has done. Then you will experience God's peace, which exceeds anything we can understand. His peace will guard your hearts and minds as you live in Christ Jesus. Philippians 4:5—7, NLT

When we worry, we are telling God, "You are neither trustworthy nor in control, so I need to worry and scheme as I take matters into my own hands." In this way unbelief drives worry, for it is impossible to worry when we are trusting in the provision of our sovereign God.

I has such a sinking in my inside I has to get up and eat biscuits.

I used to worry about every little thing, trying to figure out every problem. Well, I realize now how foolish that was. I was no more in control of my life than the man on the moon.

No man is without his load of trouble.

Only by trusting in God can a man carrying responsibility find repose.

I am an old man and have had many worries, but most have never come to pass.

Not worrying is a skill. It's a skill not breaking down every single moment.

A Christian ought to realize what the weights laid on his spirit are. If he encounters it in the morning and does not deal with it at once, he experiences defeat the whole day long.

Worry is the interest paid by those who borrow trouble.

Everything I ever worried about turned out exactly as it was going to, despite my anxious moments to the contrary.
