Ref: Hebrews 9:28.
The Christian idea of salvation relates to past, present, and future. The Bible says, “By grace you have been saved through faith” (Ephesians 2:8). It says that the gospel is the power of God “to us who are being saved” (1 Corinthians 1:18). And it says, “Salvation is nearer to us now than when we first believed” (Romans 13:11). We have been saved. We are being saved. We will be saved.
At every stage we are saved by the death of Christ. In the past, once for all, our sins were paid for by Christ himself. We were justified by faith alone. In the present, the death of Christ secures the power of God’s Spirit to save us progressively from the domination and contamination of sin. And in the future, it will be the blood of Christ, poured out on the cross, that protects us from the wrath of God and brings us to perfection and joy.
Until we feel some measure of dread about God’s future wrath, we will probably not grasp the sweetness with which the early church savored the saving work of Christ in the future: “[We] wait for his Son from heaven, whom he raised from the dead, Jesus who delivers us from the wrath to come” (1 Thessalonians 1:10). Jesus Christ, and he alone, can save us from the wrath to come. Without him, we will be swept away forever.
