On Robert Henderson's Courtroom model of prayer Christ has to continually offer his blood before God as an atonement for sin, contra the teaching of scripture that Christ died once for all. 

Can he dispense with this part of the model without loosing the whole thing?
Can he avoid the implication that Christ's sacrificial death on the cross was not enough?

Your thoughts are welcome.
