Son of God
Mark 2:6 But there were certain of the scribes sitting there, and reasoning in their hearts,
Mark 2:7 Why doth this man thus speak blasphemies? who can forgive sins but God only?
Good question; it is true that only God can forgive sins. For the skeptics, this is proof that Jesus was God's son who is one with the Father.
Mark 2:8 And immediately when Jesus perceived in his spirit that they so reasoned within themselves, he said unto them, Why reason ye these things in your hearts?
Jesus always new their thoughts.
Mark 2:9 Whether is it easier to say to the sick of the palsy, Thy sins be forgiven thee; or to say, Arise, and take up thy bed, and walk?
Words are cheap, but to see someone healed, that is miraculous.
Mark 2:10 But that ye may know that the Son of man hath power on earth to forgive sins, (he saith to the sick of the palsy,)
Mark 2:11 I say unto thee, Arise, and take up thy bed, and go thy way into thine house.
The miracle was the evidence that Jesus was God's son who also can forgive sins.
Mark 2:12 And immediately he arose, took up the bed, and went forth before them all; insomuch that they were all amazed, and glorified God, saying, We never saw it on this fashion.
God came down to man and they beheld his glory.
John 1:14 And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.
The Living Word brought with him healing and the forgiveness of sins.
