You little know what you have done, when you have first broke the bounds of modesty; you have set open the door of your fancy to the devil, so that he can, almost at his pleasure ever after, represent the same sinful pleasure to you anew.

Prayer must carry on our work as much as preaching; he preacheth not heartily to his people that will not pray for them.

Make careful choice of the books which you read: let the holy scriptures ever have the pre-eminence, and, next to them, those solid, lively, heavenly treatises which best expound and apply the scriptures, and next, credible histories, especially of the Church... but take heed of false teachers who would corrupt your understandings.

The heart is naturally hard, and grows harder by custom in sin, especially by long abuse of mercy, neglect of the means of grace, and resisteing the spirit of grace.

See that your chief study be about heart, that there God's image may be planted, and his interest advanced, and the interest of the world and flesh subdued, and the love of every sin cast out, and the love of holiness succeed; and that you content not yourselves with seeming to do good in outward acts, when you are bad yourselves, and strangers to the great internal duties. The first and great work of a Christian is about his heart.
