Jesus' sacrifice on the cross was for everyone. It was complete. The agreement made between God and Jesus was fulfilled. Jesus secured salvation for “whoever believes.” But Jesus' work did not end. His work continued in the Holy Place, then in 1844 progressed to the Most Holy Place in the most solemn work of the Investigative Judgment.

Before the foundations of the earth were laid, the Father and the Son had united in a covenant to redeem man if he should be overcome by Satan. They had clasped Their hands in a solemn pledge that Christ should become the surety for the human race. This pledge Christ has fulfilled. When upon the cross He cried out, “It is finished,” He addressed the Father. The compact had been fully carried out. Now He declares: Father, it is finished. I have done Thy will, O My God. I have completed the work of redemption. If Thy justice is satisfied, “I will that they also, whom Thou hast given Me, be with Me where I am.” John 19:30; 17:24. (DA 834.2).

The earth was rent by a terrible earthquake as the Redeemer of the world died, a sacrifice for guilty man; that the transgressor of God's holy law might be restored to the favor of the Father, and fitted for the society of heaven. He carried out the plan of salvation, and Satan was vanquished by the power of the Conqueror. (RH October 9, 1888, par. 9).

The atoning sacrifice is full and sufficient. It is the new covenant, sealed with His blood, which was shed for many for the remission of sins. (5BC 1102.6).

The great sacrifice of the Son of God was neither too great nor too small to accomplish the work. In the wisdom of God it was complete; and the atonement made testifies to every son and daughter of Adam the immutability of God’s law. ST December 30, 1889, par. 1
