A man who has no part in the grace of God, cannot keep the commandments of God, or prepare himself, either wholly or in part, to receive grace; but he rests of necessity under the power of sin.

When I am angry I can write, pray, and preach well, for then my whole temperament is quickened, my understanding sharpened, and all mundane vexations and temptations depart.

He who believes in God is not careful for the morrow, but labors joyfully and with a great heart. "For He giveth His beloved, as in sleep." They must work and watch, yet never be careful or anxious, but commit all to Him, and live in serene tranquility; with a quiet heart, as one who sleeps safely and quietly.

The cross alone is our theology.

God is ready to give more quickly, and to give more than you ask; yea, he offers his treasures if we only take them. It is truly a great shame and a severe chastisement for us Christians that God should still upbraid us for our slothfulness in prayer, and that we fail to let such a rich and excellent promise incite us to pray.

What are the things we should pray for? First, our personal troubles...The greatest trouble we can ever know is thinking that we have no trouble for we can become hard-hearted and insensible to what is inside of us.

There is on earth among all dangers no more dangerous thing than a richly endowed and adroit reason...Reason must be deluded, blinded, and destroyed.
