It is not only prayer that gives God glory but work. Smiting on an anvil, sawing a beam, whitewashing a wall, driving horses, sweeping, scouring, everything gives God some glory if being in his grace you do it as your duty. To go to communion worthily gives God great glory, but to take food in thankfulness and temperance gives him glory too. To lift up the hands in prayer gives God glory, but a man with a dung fork in his hand, a woman with a slop pail, give him glory too. He is so great that all things give him glory if you mean they should. So then, my brethren, live.
