The glorious angels, who, for burning in fervour and devotion, are called seraphim, are chosen by God to serve Him in heaven. The snail under the law was unclean, because a dull, slothful creature. Obedience without fervency, is like a sacrifice without fire. God deserves the flower and strength of our affections. Domitian would not have his statue carved in wood or iron, but made of gold.
Lively affections make golden services.
It is fervency that makes obedience acceptable. Elijah's prayer fetched fire from heaven, because, being fervent, it carried fire up to heaven. Obedience must be extensive, it must reach to all God's commands. There is a stamp of divine authority upon all God's commands, and if I obey one precept because God commands, I must obey all. True obedience runs through all duties of religion, as the blood through all the veins, or the sun through all the signs of the zodiac.
