But wisdom is proved right by all her children

Luke 7:24-50
This is the one about whom it is written: “‘I will send my messenger ahead of you, who will prepare your way before you.’  I tell you, among those born of women there is no one greater than John; yet the one who is least in the kingdom of God is greater than he.” This is the John Baptist.
For John the Baptist came neither eating bread nor drinking wine, and you say, ‘He has a demon.’The Son of Man came eating and drinking, and you say, ‘Here is a glutton and a drunkard, a friend of tax collectors and sinners.’ But wisdom is proved right by all her children. 

Therefore, I tell you, her many sins have been forgiven—as her great love has shown. But whoever has been forgiven little loves little.
Jesus said to the woman, “Your faith has saved you; go in peace.”
This is a different incident from the one recorded in the other Gospels. Simon shows Jesus no special courtesy. But a common prostitute, to whom he has opened up the possibility of forgiveness, pours out her gratitude in lavish love, not caring what anyone thinks. Jesus reads Simon's thoughts and takes them up in his story. The woman's love does not earn forgiveness, it follows it.
Why?
But wisdom is proved right by all her children. Only one who follows Jesus have real wisdom from the Lord. 
Women's faith save her and earned forgiveness.
John Baptist is the one greatest in the world, who is Jesus messenger ahead of Jesus.
Jesus has the authority to forgive one's sins. For Jesus is son of God.
Love Jesus more has faith in Jesus, so earn forgiveness much more.
She knew sins, and confessed she has sins. She knew who is Jesus and know he will forgive her sins.
How?
Do I sensed I have sins? Yes. I do. Only the sinner who needs Jesus.
