In life (time), we all go through some things - we should all have some scars as a result. Scars are connected to stories: regardless of wet her they are physical or mental, scars.
Scars. Forgive, but never forget the scar/story.
The Cross of Christ, was connected to purpose. A lot of hate was involved in the murder of Christ. A crowd(mainly Kenites) chanted "crucify Him" - "let His blood be upon us, and our children(Mat27:25)."
The Apostle Thomas was not present when Christ-Jesus met with some of the Disciples: "Except that I see in His hands the print of the nails, and put my into the print of the nails, and thrust my hand into His side, I will not believe."
Apostle Thomas actually represent many of us: who are just to timid to speak their mind. Christ responded then, and will even now.
8 days later Christ appeared again, Thomas was present this time.
Then said Christ-Jesus unto Thomas: " Reach here with thy finger, and behold My hands. Thrust your hand into My side, and be not faithless." (Jn.20:24-28). Thomas response: "My LORD and My GOD."
For many of us, the Scars told the whole story. The prophecy, the Life, the death, and the resurrection. The LORD on the Cross " Father forgive them, they know not what they do." The Scars, stayed, even with forgiveness.
