A Discovery For Me...No Doorknob

As many times as I have seen this painting I have always missed the fact that the doorknob is missing. 

For sure I knew Christ was knocking at my door and often I would say come in.  But how could He?  There is no doorknob.  He is waiting for me to open to Him.

His knock is calling me to have compassion, mercy, forgiveness, to all, even to the ones who don't deserve it.  I hear the knocking but how often I say I don't want to forgive.  I will not have compassion.  I will not go out of my way; let someone else do it.  I will not open my heart, my door.

Lord, help me to open to you in every situation.
