Despite the fact that the power of the Almighty God resurrected Jesus, the one who laid down His life willingly, He (God) did not remove all the scars from His anointed one's body. This seems strange at first. When I imagine God restoring life to Jesus, or to any of us when all of Creation is restored, I imagine being totally new and also free from any deformities or flaws. I imagine crippled friends being able to walk, I imagine friends who suffer from chronic pain being able to move freely, I imagine depressed friends being able to laugh. So why wouldn't God remove all of Jesus' deformities, the burdens of His mortal life?
Carl Heinrich Bloch, 1881
So why did these scars remain? This is what I think (another guess). The scars that remained, whether just those mentioned in Scripture or more, were not "healed" because they were part of Jesus' "new man." Though on earth scars are often ugly and painful, in God's restored order they can be like a crown of jewels. Jesus' scars displayed the glory of God working through His life.
I believe earthly burdens will be finally laid down. But I also believe that the growth and sacrifice we experience on earth, however painful it might be here and now, will not be discarded but will be celebrated for what it truly is - the glory of God. We all have scars, and I rest assured that we will be fully healed from every last one whether it is today or in the days to come, but God is the one who knows which scars are to be healed and which are to be worn as a crown.
