If the blood Jesus shed before and at the cross was preserved and you took a bath in it, would it take away even one sin?
The men who whipped Jesus were covered with his blood and it only made them bloody sinners.
If Jesus had been tied to the cross and poisoned would his death have covered our sins?
New American Standard Bible (©1995) Romans 5-10
For if while we were enemies we were reconciled to God through the death of His Son, much more, having been reconciled, we shall be saved by His life.
