When does God activate the payment of the sin debt?
The sin debt is already paid in full, but God does not activate that payment until a person believes the Gospel. Belief is the condition for appropriating forgiveness; without faith in the Gospel, the payment remains unapplied. For those who do believe, they are totally forgiven and their sins are canceled.
Les teaches that the sin debt is already paid in full through the atoning blood, but God cannot activate that payment until a person believes the Gospel. He emphasizes that if someone goes into a lost eternity, it is not because their sins were not taken care of or because the atoning blood was not for them, but because they rejected it in unbelief. Belief is the requirement to appropriate forgiveness; those who believe are totally forgiven. He also connects this to Colossians, where we are told to forgive one another as Christ forgave us, and that believers are forgiven all sins and trespasses. At the judgment seat of Christ, believers will not have to face their sin because it is taken care of, forgiven, and canceled.
