Faith?

What is your first reaction when a dear loved one wrongs you or makes a mistake that really only hurts themselves? Do our own personal life experiences, shape and mold the way we react or can we choose to change our thinking based on something else? It makes me sad, how quick people can lose their Faith, because they feel someone they care about is doing something "stupid", when really they are only hurting themselves. I'm not sure if it's because I'm a mom, or that I personally have made MANY mistakes, or if it's my spirituality but I only FEEL for my friends who go through hard times and make wrong decisions. If we slander them or get angry and lose faith in them as people when they mess up, how can we truly accept them back when they realise what they've done and come back asking for help? The prodigal son comes to mind and how the brothers of this man hated him for the wrong he had done and didn't think their father should welcome him back, but the father saw the remorse in his heart and welcomed him back. Not to say that this is an easy way to naturally think, especially when we feel wronged or hurt...but how would we want to be treated if we were in their situation? Would we not want the DIGNITY to have a change of heart and have our loyal friends there waiting for our return? Maybe some cant grasp this, because they have never had to go through it...but can that really be an excuse for everything? Must we mess up in life to understand redemption, or can we use our deep love for others to drive our ability to understand to live and let live? How can we expect the ransom to cover our sins, but not the sins of others?
