From John MacArthur, Jr., in Found: God’s Peace — Experiencing True Freedom From Anxiety in Every Circumstance
Recall that Jesus said, “Look at the birds of the air, that they do not sow, nor reap nor gather into barns, and yet your heavenly Father feeds them. Are you not worth much more than they?” (Matt. 6:26). Martyn Lloyd-Jones, commenting on that verse, explained:
Faith, according to our Lord’s teaching … is primarily thinking.… We must spend more time in studying our Lord’s lessons in observation and deduction. The Bible is full of logic, and we must never think of faith as something purely mystical. We do not just sit down in an armchair and expect marvelous things to happen to us. That is not Christian faith. Christian faith is essentially thinking. Look at the birds, think about them, and draw your deductions. Look at the grass, look at the lilies of the field, consider them.… Faith, if you like, can be defined like this: It is a man insisting upon thinking when everything seems determined to bludgeon and knock him down.… The trouble with the person of little faith is that, instead of controlling his own thought, his thought is being controlled by something else, and, as we put it, he goes round and round in circles. That is the essence of worry.… That is not thought; that is the absence of thought, a failure to think.
