"'When I broke the five loaves for the five thousand, how many basketfuls of pieces did you pick up?' 'Twelve,' they replied. 'And when I broke the seven loaves for the four thousand, how many basketfuls of pieces did you pick up?' They answered, 'Seven.' He said to them, 'Do you still not understand?'" NIV translation
The conversation continues as Jesus reminds them of the fact that He had fed all of those people when it did not seem possible. Their part in the feeding of the people had simply been to deliver what the Lord had provided. All the people had to do was to accept the food as a gift from God. He had been sufficient for the physical needs and He is sufficient for their spiritual need of salvation.
This is a picture of how we are to share our faith with the world. As disciples, we are to simply take the gift that God has provided and present it to those that do not know Him. Then, they can simply accept the gift or refuse it.
"They came to Bethsaida, and some people brought a blind man and begged Jesus to touch him. He took the blind man by the hand and led him outside the village. When he had spit on the man's eyes and put his hands on him, Jesus asked, 'Do you see anything?'" NIV translation
Once again, they came to Bethsaida known as the house of fish and the hometown of some of the disciples. Again, a blind man was brought to Jesus to be healed but we notice that he took the man out of the town before He healed him. The town had become like Nazareth in the fact that they had seen the miracles of Jesus but rejected Him. This time Jesus spit on the man's eyes which speaks of the words of God.
The town was a religious town and had knowledge of the things of God but still could not see Jesus as the promised Messiah.
The same type of thing is happening today in the local "churches". Many have a religious tradition but no room for the work of the Lord. Very little happens there like a tree that does not produce any fruit. But, Jesus is taking many of His people by the hand and leading them outside of these "churches" where there is room for Him to work.
"He looked up and said, 'I see people; they look like trees walking around.' Once more Jesus put his hands on the man's eyes. Then his eyes were opened, his sight was restored, and he saw everything clearly. Jesus sent him home saying, 'Don't go into the village.'" NIV translation
When the man first opened his eyes, he could not clearly see so Jesus put His hands on him again. Why did He have to do so twice? This was a picture of the fact that even the people of that religious town could be saved if they would only yield to the touch of Jesus. Why did Jesus tell the man not to go back into the town? They had already seen the miracles that Jesus performed and still did not believe.
