“Do not content yourselves with being in a state of grace, but also be careful that your graces are kept in vigorous and lively exercise, and that you preach to yourselves the sermons which you study, and do so before you preach them to others. If you did this for your own sakes, it would not be lost labor; but I am speaking to you for the public’s sake, so that you would do it for the sake of the Church. When your minds are in a holy, heavenly frame, your people are likely to partake of its fruits. Your prayers, and praises, and doctrine will be sweet and heavenly to them. They will likely sense when you have been with God extensively: what is most on your heart, is likely to be most in their ears.”
