A few days later, when Jesus again entered Capernaum, the people heard that he had come home. 2 So many gathered that there was no room left, not even outside the door, and he preached the word to them. 3 Some men came, bringing to him a paralytic, carried by four of them. 4 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. 5 When Jesus saw their faith, he said to the paralytic, “Son, your sins are forgiven.”
6 Now some teachers of the law were sitting there, thinking to themselves, 7 “Why does this fellow talk like that? He’s blaspheming! Who can forgive sins but God alone?”
8 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? 9 Which is easier: to say to the paralytic, ‘Your sins are forgiven,’ or to say, ‘Get up, take your mat and walk’? 10 But that you may know that the Son of Man has authority on earth to forgive sins…” He said to the paralytic, 11 “I tell you, get up, take your mat and go home.” 12 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!”
Check out verses 6-8 for a moment, for they get lost in the shuffle of Jesus laying indirect claim to His divinity here via the healing. He could read thoughts. This goes beyond the standard divine omniscience of seeing everything, going into our thought life.
People get nervous about the idea of a Google Maps film crew catching them in their PJs getting the newspaper off the front porch or some government drone catching them doing something funky in their back yard. God has that beat in spades, and if you know God is watching, knowing that someone else might have a peek as well should be secondary... assuming you have next to nothing to hide in the first place.
Even our thoughts are known to God, so trying to put on a facade for Him won't work.
