One sacrifice, however great, is insufficient to pay the debt of sin. The atonement requires constant self-immolation on the sinner's part. That God's wrath should be vented upon His beloved Son, is divinely unnatural. Such a theory is man-made. … The material blood of Jesus was no more efficacious to cleanse from sin when it was shed upon 'the accursed tree,' than when it was flowing in his veins as he went daily about his Father's business. … His disciples believed Jesus to be dead while he was hidden in the sepulchre, whereas he was alive.
