In the scripture the terms “salvation” and “deliverance” have similar meanings, but not the same. Deliverance usually is in the context of judging an enemy to rescue someone out of slavery and trouble. This is seen in Israel crossing the Red Sea and the Egyptians were drowned in it. Salvation includes this, but it also means more (Heb. 9:28). On this judgement aspect the two terms are interchangeable.
When Jesus mentions in John 16 that the Holy Spirit “correct the world about judgment, because the ruler of this world has been judged,” this is what we mean by deliverance. Judgement is referring to all aspects of power and command that belongs to a ruling king. Salvation is this and the addition of His positive works of righteousness freely given (Romans 5) and positive blessings given to us by His Contract in blood (Hebrews 8).
Jesus executes judgement on Satan by binding him up and blundering his house.
“But if it is by the Spirit of God that I drive out demons, then the kingdom of God has come upon you. “Or again, how can anyone enter a strong man’s house and carry off his possessions unless he first ties up the strong man? Then he can plunder his house. “Whoever is not with me is against me, and whoever does not gather with me scatters,” (Matthew 12:28-30 NIV). (see Acts 10:38, Heb. 2:10-14, Colossians 2:15)
Jesus is the caption of salvation for His chosen ones. Satan is the chief enemy against Jesus’ kingdom, and thus, the King must deal with Satan to show His power. Jesus does this. Jesus removes the dominion of Satan and replaces it with His dominion. This is Jesus’ judgment and deliverance. The Holy Spirit corrects the souls of men about this, because they have sided with Satan against the Kingdom of God. Satan is defeated; his kingdom is weakening. Soon he, and all who align with his rule, will be thrown into hell. But Jesus’ kingdom will last forever and ever, amen.
In Satan’s dominion, his law was a law of accusation, bondage, and fear. Jesus defeated this. He obtains His Kingdom by war and conquest. Jesus bound, plundered, and casts out Satan; He neutered his power and accusations against His chosen ones. Jesus came to earth and by His power, even power showed in sacrifice, defeated Satan in battle. Jesus is a mighty warrior. The devil defied the saints of God. Jesus with one stone, killed Satan and cut off his head. In Jesus’ atonement and resurrection, it was 100 times truer, “Today the whole world will know there is a God in Israel.”
“Now is the time for judgment on this world;
now the prince of this world will be driven out.”
In Jesus’ dominion, He rules with the law of unmerited favor and sonship. The Father has transferred us from the kingdom of darkness into the Kingdom of the Son of His love (Colossians 2:13). These additional super blessings of being sons of God, even co-heirs with Jesus and being highly favored by God and not merely forgiven and in a neutral standing with God, is the fuller meaning of “salvation.” The word salvation can mean just judgement or the fuller meaning depending on context. David often used salvation as God both delivering him, and setting his feet in a good and prosperous place. Jesus does this for all His saints through His atonement.
The substitutionary atonement of Jesus is both a deliverance in power and a substitutionary exchange were Jesus gives us His righteousness and highly favored status. Thus, the finished atonement of Jesus is the fuller meaning of salvation.
