The road is rugged, and the sun is hot. How can we be but weary? Here is grace for the weariness – grace which lifts us up and invigorates us; grace which keeps us from fainting by the way; grace which supplies us with manna from heaven, and with water from the smitten rock. We receive of this grace, and are revived. Our weariness of heart and limb departs. We need no other refreshment. This is enough. Whatever the way be – rough, gloomy, unpleasant – we press forward, knowing that the same grace that has already carried thousands through will do the same for us.
