Atonement: The Death, Burial, and Resurrection of The Lord Jesus Christ is the sacrificial atonement for the sins of humanity, reconciling people to God.
It is why 2C5.org exists and we can say God is in Christ Jesus reconciling the world back to Himself NOT counting our trespasses against us.
The atonement is everything to the believer — it’s why we can say we are forgiven and do not deserve punishment or the curse’s consequences — which is sickness, poverty, chronic foolish decisions that produce failure.
