How can Blood make us white as snow?

Today in my devotions I was reflecting on Mark 15:38...
"The curtain of the temple was torn in two from top to bottom."
I began to go deep into the blood of the Lamb and was rejoicing in what we have through the blood. In the Old Testament the only one who could go into the Holy of Holies once a year was the high priest...only once a year, but when Jesus died on the cross it reconciled us to the Father...there no longer needed to be a curtain...we have ALL been given full access. We no longer needed a sacrifice to atone for our sins...Jesus was that perfect sacrifice without spot or blemish. He was the sacrifice for our past, present and future sins. Through His death we have forgiveness and cleansing...we are made NEW! Man, when I think about how He has forgiven me...how can I not forgive others, how can I hold offenses towards other. What if God did that to me? Through His death we have wholeness and healing. The Bible says in Isaiah 53:5, "But he was pierced for our rebellion, crushed for our sins. He was beaten so we could be whole. He was whipped so we could be healed.
Thank you God for sending your Son Jesus to die on a cross for me, because you loved me THAT much. Thank you Lord for what I have received through your blood...the blood of Jesus!
