I indebted this to one my teachers, Dr Danny 
It's really a wonderful retreat, a unique experience, as well as oppurtunity to explore things otherwise i will never try out.
In the afternoon, we're given enough time to meditate on Luke 15, and look upon copy of Rembrandt painting...Parable of Prodigal Son. It's a well known story, that I've heard over and over again, probably could tell it out of head. However, i gave it a try, to read again afresh. And really amazed on how much things I didn't see earlier. Besides thanks to my schoolmate, who earlier pointed me out to so much rich treasure lied there. Here the reflection based on the 3 main character in the story:
1. The undeserved younger son.
I encountered it afresh. It must have shocked Jesus' audience that time. For it was told that this younger son one day came to see his father. THEN, he asked for his share!!! How DARE this boy asked such thing?!! Then when the father agreed, the next thing even more staggering. He left the house!!! Oh....his sins were so grieveous and ill that one could not wish any good for him. Except for him to go to HELL and perish. I could hear the hearers hissed....get lost with this man. He has treated his father with such manner, and he deserved Heaven's worst punishment.
Then when the story continued, this man became poor and needy. Oh, i think, how glad the hearers must have rejoiced in their hearts. And when he fought with the pigs for food....oh how just God must be. He got what he deserved. Let him die soon. He DESERVED that.
2. The pitiful older son
I saw a picture of very sad reality. I understood the painting wrongly (identified someone who's not as the older brother). However, here my interpretation of the story and the painting. The older son look with disbelief face, when the father accepted his brother. For how can he believed what he see, when the father embraced the rightly condemned brother. Oh how can this man who sin so greatly, yet been forgiven? Let him be cursed!! Cursed is he!! He deserved worst kind treatment. He supposed to be treated as ANIMAL. And his hands pressed hard on his chest. For he says "I could not accept this." And his face was angry too...with kind disbelief and astonishment..."I could not accept this. This is a MISMATCH. It is just NOT FAIR.
Is it then how i react when other people accepted into God's family? Is it how i response in my heart when others come to know the Lord? Do i also see with such jealousy? Or prejudice in my heart, saying "what right do this wretched has?"
3. The scandalous father
Here i think the most significant and best character in the story. For there the Bible puts clearly what God's heart look like. For since the day the younger son left the house, the father always standing, watching, waiting, for the day he will see his son coming home. He didn't cast out hope that one day his son will come back. No. He stood, waited, and watched .......... Till the day finally came. And when he saw his son from far........he recognize, it was his son. He could identified...it was his son, though probably others can't recognize him anymore.....evenso from afar. Then this father ran towards him, kissed him, embraced him.
The painting puts it very well. For the hands that embraced that WRETCHED son speak of volumes. The hands at his back speaks of COMFORT and assurance. It comforts him...that it's well. All is well!! And it assures him also, saying "You are forgiven!! YES, you are forgiven!! No matter how wrong, and how bad your offenses are. They all PARDONed!! What a scandalous loving father. No small wonder the older son could not understand him. For this action was totally unreasonable and unbecoming. That this offensive son was treated that manner.
Oh, but look at that wretched son. His head rested on his beloved father's bosom. It rested there, secure and comforted. He felt his father understood. For truly his father understood. And he cried "What a father that i have. What a father." "What a grace." "This is so overwhelming." It is. But exactly so, because it's grace. Grace is overwhelming. And i believe, that son, would be a total new person. He is a changed man, a totally new being. For he was blind but now sees. Was lost, but now found. I believe, that son would never depart from his father's house again. Forever he will stick by his father's side. For he knows how much his father loves him.
Oh...such is the heart of God. Always longing, always beating, always waiting for the lost to return and be saved. That none should perish. Be it the potter's heart in Jeremiah 18 who longs for the people to repent and reshaped back instead facing destruction. Or the father's heart who desiring his son to come home. We see clear enough. To some, he's a scandalous father. Totally unbecoming. Totally absurd and totally no sense of justice. However i'm glad for the fact God is portrayed as such. How i love that father. And the song Amazing Grace speaks appropriately. How amazing, how sweet the sound that saved a wretched like me. Was blind but now I see.
