Thinking About Miracles
I believe that miracles had a distinct purpose. Look with me at what Jesus said, "The works which the Father has given me to accomplish, the very works that I do, bear witness to me that the Father has sent me" (John 10:25). Add to this clear verse, John 10:38 and 14:10,11. So, the miracles (works) bear witness (verify) that Jesus was sent from God.
Sometimes miracles were to demonstrate some important teaching.
A very clear example is given in Mark 2:1-12. When the paralytic was let down through the roof for Jesus to heal him, Jesus said, "Son, your sins are forgiven." Scribes who were in the crowded house thought Jesus was blaspheming in claiming to forgive sins.
Jesus answered their thoughts, “Why reason ye these things in your hearts? 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? 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,) I say unto thee, Arise, and take up thy bed, and go thy way into thine house.” And he did!
So, Jesus had authority to forgive sins...we KNOW because of the miracle of healing.
"We have never seen anything like this" (Mark 2:12). NASB
Most often miracles were to confirm a message.
A supernatural message must have supernatural documentation. Miracles provided that supernatural evidence. Otherwise, how would we know thatthe message was from God?
