Authority by healing people

He said to them, "If any of you has a sheep and it falls into a pit on the Sabbath, will you not take hold of it and lift it out? How much more valuable is a man than a sheep! Therefore it is lawful to do good on the Sabbath."

(Matt 12:11-12)

The LORD denies the religious excuses made to avoid meeting real human need.

A few days later, when Jesus again entered Capernaum, the people heard that he had come home. So many gathered that there was no room left, not even outside the door, and he preached the word to them. Some men came, bringing to him a paralytic, carried by four of them. Since they could not get him to Jesus because of the crowd, they made an opening in the roof above Jesus and, after digging through it, lowered the mat the paralyzed man was lying on. When Jesus saw their faith, he said to the paralytic, "Son, your sins are forgiven."
Now some teachers of the law were sitting there, thinking to themselves, "Why does this fellow talk like that? He's blaspheming! Who can forgive sins but God alone?"

Immediately Jesus knew in his spirit that this was what they were thinking in their hearts, and he said to them, "Why are you thinking these things? Which is easier: to say to the paralytic, 'Your sins are forgiven,' or to say, 'Get up, take your mat and walk'? But that you may know that the Son of Man has authority on earth to forgive sins . . . ." He said to the paralytic, "I tell you, get up, take your mat and go home." He got up, took his mat and walked out in full view of them all. This amazed everyone and they praised God, saying, "We have never seen anything like this!"

(Mark 2:1-12)

When the people set a needy man right in front of the One declaring the truth, did He treat that practical portion of ministry as secondary to preaching? On the contrary. He was able to incorporate helping the man as a demonstration of his very lesson. The man rejoiced. The people learned God's truths. And, trust in Christ was made to increase.
