Several years ago I broke my wrist in three places. I went to the doctor and he set it and put a cast on it. It took it longer than usual to heal but it did heal. There are times now though it will ache.
It is a different kind of wound but the majority of us have had a wounded heart. Nothing will help but going to the Great Physician. Only He can mend a broken heart. It too takes time and may ache for a long time to come but He does promise healing. His love is the medicine that must be applied over and over.
It may take others praying over you and even helping you cut into the infected heart. It can be extremely painful. The lancing of the heart brings poison to the surface that may have aded in addictions, trouble relationships, dysfunctions from work to how you are able to enjoy God and others. It is not an excuse for these things but it is to understand the root of where they may stem from.
