Luke 9:6

‘And they departed, and went throughout the villages, preaching the good news, and healing everywhere.'

Thus they went on their way, and went through the villages preaching the Good News of the presence of the Kingly Rule of God, and the need for response to it, and along with their preaching they ‘healed everywhere'. The Old Testament promises were in process of fulfilment. The blind were seeing, the deaf were hearing, the dumb were speaking, the lame were walking (Isaiah 35:5). The Apostles, some of whom had listened to both John the Baptiser and Jesus preaching on repentance and forgiveness, would know in general what to preach. And as the Kingly Rule of God had been central in Jesus preaching they would know well what He had taught. They were thus not short of material. Their problem would arise when they were asked the kind of question that appears in the next verse. Otherwise they were sufficiently equipped for an elementary ministry, and would learn hugely from it.
