The seed of every sin is in every heart.

If private revelations agree with Scripture, they are needless, and if they disagree, they are false.

...but let it suffice us to know that it became God, who is the supreme Ruler, Governor and Judge of all that sin should be punished with death in the sinner or his surety; and therefore if God would bring many sons to glory, the Captain of their salvation must undergo sufferings and death, to make satisfaction for them.

He, then, that would really, thoroughly, and acceptably mortify any disquieting lust, let him take care to be equally diligent in all parts of obedience, and know that every lust, every omission of duty, is burdensome to God, though but one is so to him.

Herein would I live; herein would I die; hereon would I dwell in my thoughts and affections; to the withering and consumption of all the painted beauties of this world, unto the crucifying all things here below, until they become unto me a dead and deformed thing, no way meet for affectionate embraces.

Ignorance of God and of ourselves is the great principle and cause of all our disquietments; and, this ariseth mostly not from want of light and instruction, but for want of consideration and application.

The duties God requires of us are not in proportion to the strength we possess in ourselves. Rather, they are proportional to the resources available to us in Christ. We do not have the ability in ourselves to accomplish the least of God's tasks. This is the law of grace. When we recognize it is impossible for us to perform a duty in our own strength, we will discover the secret of its accomplishment.
