Quick must be the hand if an impression is to be made upon the melted wax. Once let the wax cool and you will press the seal in vain. Cold and hard it will be in a few moments, therefore let the work be quickly done. When men's hearts are melted under the preaching of the Word, or by sickness, or the loss of friends, believers should be very eager to stamp the truth upon the prepared mind. Such opportunities are to be seized with holy eagerness. Reader, do you know of such? If you be a lover of the Lord Jesus, hasten with the seal before the wax is cool.
