In my life I have at times lived the role of each of the individuals in the story, but by far, the most challenging has been the role of the younger brother. It seems that time after time, day after day I go to the Lord in prayer to forgive me of my sins, and I know that He has. Knowing that the people I've harmed are going through a hard time in their life due to something I've done can cause unbearable shame and regret. In my heart I know that God has forgiven me. The ability to receive forgiveness from myself and others takes longer, sometime a lifetime, but it is worth pursuing. By surrendering this part of our life to God and making amends to others will draw us nearer to Christ and will help in our own walk of faith as others do harm to us.
This book below is an excellent work that breaks down the story in great detail, looking at the story from several different points of view. I hope this story will bless your life as it has mine.
