A certain Pharisee invited Jesus to dine with him, and he entered the Pharisee’s house and reclined at table. Now there was a sinful woman in the city who learned that he was at table in the house of the Pharisee. Bringing an alabaster flask of ointment, she stood behind him at his feet weeping and began to bathe his feet with her tears. Then she wiped them with her hair, kissed them, and anointed them with the ointment.  Luke 7:36-38 

Reflect, today, upon your own sin.  Unless you know your sin, you cannot manifest this type of humble sorrow.  Do you know your sin?  From there, consider getting down on the ground, on your knees, bowing your head to the ground before Jesus and sincerely begging for His compassion and mercy.  Try literally doing that.  Make it real and total.  The result is that Jesus will treat you in the same merciful way He did this sinful woman.
