What does Hebrews 10:18 mean?
This verse completes the writer's long explanation of the superiority of the new covenant. Earlier, the writer had made a powerful point about the animal sacrifices of the old covenant. Since they were offered over and over, it was clear they could not actually take away sin (Hebrews 9:8–10). If they could, the priests would have stopped offering them (Hebrews 10:1–2). Instead, they continued to bring animal blood, in obedience, and as a reminder of sin (Hebrews 10:3–4).Sacrifice was described as absolutely necessary for the forgiveness of sins (Hebrews 9:22). However, animal blood could not accomplish the salvation of man. It could settle ceremonial issues, but not change the sinful inner being. Christ's sacrifice, on the other hand, was entirely human, and entirely perfect. This is why Jesus is described as "seated" in heaven, symbolizing His finished work (Hebrews 10:12).
As the writer points out here, when sin is truly forgiven, there "is no longer any offering." This means that once a truly saving sacrifice has been offered, there is no reason to offer any further sacrifices for sin. An additional meaning to this statement, given later, is a warning. Those who turn away from Jesus are abandoning the one and only remedy for their sin.
Hebrews 10:1–18 summarizes the writer's argument that the new covenant, in Jesus Christ, is superior to the old covenant, based on animal sacrifices. Using themes developed in earlier passages, this section points out that God's own Word promised to replace the system centered on the priests and the temple. Those flawed earthly components were symbols of the ''real'' remedy for sin, which is the one-time sacrifice of Jesus. Having completed this long, detailed discourse, the writer will move on to practical applications, including a very stern warning.
God's own words, found in the Old Testament Scriptures, declare His intention to replace the old covenant with a new covenant. Jesus fulfills all of these prophecies, and all of the symbolism found in the system of priests, the tabernacle, and animal sacrifices. Knowing that Jesus Christ is, undoubtedly, God's remedy for our sin, we should be encouraged in holding on to our faith in the face of persecution. However, that same confidence means dire spiritual consequences for those who know Christ's salvation, but choose to act in defiance of His will.
