Sin hurts. 

When a Christian fails or falls into sin, all who love them are wounded by what they do. The Savior is insulted by the deed. And most difficult to repair, the world has one more compelling reason to think we are all fools for believing Christ and trusting his promises. Your sin makes Christ appear to be an inglorious liar. 

Guard your heart. Christians are connected to every other redeemed person. We are members of one another. When you fail, we all who know you feel it. We all grieve what you have done. We who love you and who love God are deeply affected by what you do in disobedience to God. So close is our connection to you, that when you fail, we are bruised. 

When we fail, the whole Church is stabbed by our treason against God. My sin affects you. You feel it with a sorrow deeper and more tender than any other human connection. When you sin, it breaks my heart. 

My sin hurts you. Your sin hurts me. Consider the price those who love you must pay when you disobey and do what you know is sin. Private sins become public. Hidden sins are brought into the light. The things done in secret are shouted from the rooftops. Of course. Jesus promised they would (see Luke 12:3). 

Your life matters. We are members one with another. We are the Body of Christ.
