Although the Christian faith has many values, virtues and applications, the most essential message is that, man a sinner, can know the fullness of forgiveness for that sin. That is the heart of the message of Christianity, and that is exactly the message of this miracle at the beginning of Matthew chapter nine.

Matthew 9:1-13

And getting into a boat he crossed over and came to his own city. And behold, some people brought to him a paralytic, lying on a bed. And when Jesus saw their faith, he said to the paralytic, “Take heart, my son; your sins are forgiven.” And behold, some of the scribes said to themselves, “This man is blaspheming.” But Jesus, knowing their thoughts, said, “Why do you think evil in your hearts? For which is easier, to say, ‘Your sins are forgiven,’ or to say, ‘Rise and walk’? But that you may know that the Son of Man has authority on earth to forgive sins”—he then said to the paralytic—“Rise, pick up your bed and go home.” And he rose and went home. When the crowds saw it, they were afraid, and they glorified God, who had given such authority to men.

As Jesus passed on from there, he saw a man called Matthew sitting at the tax booth, and he said to him, “Follow me.” And he rose and followed him.

And as Jesus reclined at table in the house, behold, many tax collectors and sinners came and were reclining with Jesus and his disciples. And when the Pharisees saw this, they said to his disciples, “Why does your teacher eat with tax collectors and sinners?” But when he heard it, he said, “Those who are well have no need of a physician, but those who are sick. Go and learn what this means: ‘I desire mercy, and not sacrifice.’ For I came not to call the righteous, but sinners.”
