Make them see & feel

Calvin said:

Let those who would discharge aright the ministry of the Gospel learn not merely to speak or to declaim, but to penetrate the consciences of men, and make them see Christ crucified, and feel the shedding of His blood. When the Church has painters such as these, she no longer needs dead images of wood and stone, she no longer requires pictures; both of which unquestionably were first admitted to Christian temples when the pastors had become dumb and been converted into mere idols, or when they uttered a few words from the pulpit in such a cold and careless manner that the power and efficacy of the ministry was utterly extinguished."
