Saint Francis of Assisi once said, "Preach the gospel always, and if necessary, use words." This was the sentiment behind Jesus' words as he sent the 72 into the surrounding villages. Preceding Jesus they were to prepare the townspeople for his coming. The preparation involved preaching, which was a sharing of who Jesus is and the context of his message. But, it is important to note, they were to stay in individuals' homes. This would mean that a very real and substantive part of their ministry would be displayed by their actions and behavior.
