There are millions of scars in a broken heart. Every turmoil causes a person to question everything and push them far away from God. It applies to many young adults especially when they are facing life's most unlikely circumstances. From my own experiences I have encountered many individuals going through heart breaks in numerous scenarios. It creates a scar and changes their perspectives of faith and spiritual connection with God. The time and process of healing varies for every individual. Despite the time and process we will be healed if we understand who would be able to heal us. Jesus Christ died for our sins and to redeem all of us. Only HE can heal any wounded soul.
