People who have been hurt will take part in hurting others, that is not a new concept, yet many have not worked towards healing the pain.
When we take time to restore broken relationships, or at least do our part in putting things right, it breaks down the potential barrier towards the Church.
Your scars remain. Your hurt is real. Acknowledge it. Don't hold it in and deal with it alone. Find someone to confide in and work things through. The pain may not go away forever, but at least you'll know you don't have to deal with it by yourself when the weather is bad.
By the grace of God I have been lifted up out of my spiritual death. I have learned from my mistakes and the hurt I held on to. Through all of that I have grown to know, God will shine through the mess.
The pain of the world is real. The struggles of life will come and they will hit hard. In fact, they might tear you down emotionally and physically..."But take heart; (Christ has) overcome the world"!
