How do we know that Christ's atonement is effectual?
Answered in 3 sources
Christ's atonement is effectual because it redeems all whom He died for, which is a truth rooted in His divine nature.
The effectual nature of Christ's atonement is affirmed in the belief that everyone for whom Christ died is wholly redeemed. As noted in the sermon, knowing Christ is integral to understanding salvation. His death was not an uncertain effort; it was definitive for those chosen by God. This is supported by verses showing that Christ's sacrifice has the power to redeem without leaving room for doubt about its effectiveness, aligning with the doctrine of Limited Atonement.
