Prepare to meet thy God, O Christian! Betake thyself to thy chamber on the Saturday night, confess and bewail thine unfaithfulness under the ordinances of God; ashamed and condemn thyself for thy sins, entreat God to prepare they heart for, and assist it in, thy religious performances; spend some time in consideration of the infinite majesty, holiness, jealously, and goodness, of that God, with whom thou art to have to do in sacred duties; ponder the weight and importance of his holy ordinances…; meditate on the shortness of the time thou hast to enjoy Sabbaths in; and continue musing…till the fire burneth; thou canst not think the good thou mayest gain by such forethoughts, how pleasant and profitable a Lord’s day would be to thee after such a preparation. The oven of thine heart thus baked in, as it were overnight, would be easily heated the next morning; the fire so well raked up when thou wentest to bed, would be the sooner kindled when thou shouldst rise. If thou wouldst thus leave thy heart with God on the Saturday night, thou shouldst find it with him in the Lord’s Day morning.
I then checked more of the search results and realized that T4G beat me there. Oh well. Still good advice.
