This is, as has been pointed out before, the way that these brethren can say that Jesus offered for himself. They say that Jesus offered for himself, and we should be satisfied. If they would say that Jesus offered for himself an atoning sacrifice for redemption of his body from sin in the flesh, we would be quite satisfied. But instead, they deny that there was any atonement involved. They deny that there is anything literal called sin in the flesh. They deny that sin nature is sin. They reason (correctly) that Jesus had to be obedient to his death on the cross, or he would not have obtained salvation. But they see obedience as the only issue, not as one of the issues, as the Truth really is. His obedience was necessary. His atonement for sin nature was also an indispensable part of his great sacrifice.
