Hebrews 9: 28 gives us GOD's Solution.
28 So Christ was once offered to bear the sins of many; and unto them that look for him shall he appear* the second time without sin unto salvation.
GOD in HIS MERCY and GRACE provided a SACRIFICIAL LAMB to ATONE for ALL OUR SIN and then HE CLOTHES US IN HIS OWN ROBE OF RIGHTEOUSNESS !
Hebrews 9:22 tells us WHY Christ HAD to SHEAD HIS OWN DIVINE BLOOD.
And almost all things are by the law purged with blood; and without shedding of blood is no remission.
Our SINS could not be PAID for in full UNLESS there was a blood sacrifice that was sufficient for all the sins of every person past, present, future.
THIS is why Christ willingly and of HIS own LOVE for His creation, MAN, went to the Cross and DIED for ALL OF US...
