Definitions of Redemption and Salvation 

To be freed from slavery or captivity.

In the absence of the triumph of the resurrection, Jesus' death would have been in vain. No matter how well-intentioned the sacrificial lamb or how honorable the cause, death by itself does not constitute a win. Christ permanently destroyed the power of death by His resurrection. Only the crucifixion could not bring about salvation. The victory of the empty tomb brought it to a close. 

What is  Redemption

To be freed from slavery or captivity.

Old Testament sacrifices were necessary to atone for the harm caused by sin.

In order to atone for the sin of the people in the tabernacle, food and animal sacrifices were offered as part of this temporary redemption. The anticipated Messiah, who would provide a last-ever blood sacrifice to atone for all sins, was what the Jewish people were waiting for. Animal offerings served to conceal sins in a temporary way, but the Messiah would do so completely.

O Israel, put your hope in the Lord, for with the Lord is unfailing love and with him is full redemption.  He himself will redeem Israel from all their sins. (Psalms 130:7) (NIV)

The promise of the Messiah was also realized in Jesus. We have been redeemed, or set free from sin, by His substitute for our sins.

But we see Jesus, who was made a little lower than the angels, now crowned with glory and honor because he suffered death, so that by the grace of God he might taste death for everyone. (Hebrews 2:9) (NAS)

Scripture's basic message about redemption is that God has taken the initiative to act kindly on behalf of those who are unable to advocate for themselves. The New Testament makes it abundantly apparent that divine redemption entails God identifying with humanity in its suffering and achieving humankind's freedom through the submission, suffering, death, and resurrection of the incarnate Son.

What Is Salvation?

According to the Bible, salvation is the process of being delivered from the inescapable effects of sin.

Did you know that the word "Jesus" means "salvation" in Hebrew?

… And you are to give him the name Jesus, because He will save His people from their sins. (Matthew 1:21) (NIV)

"It is not the healthy who need a doctor, but the sick. I have not come to call the righteous, but sinners." (Mark 2:17) (NIV)

Jesus came to “seek and to save the lost” (Luke 19:10)Jesus gave everyone of us a way to be absolved of our sins via the redemption provided by His death and resurrection, giving us the opportunity to spend eternally with Him in heaven. All we have to do is accept His invitation.

"I tell you the truth, whoever hears my word and believes him who sent me has eternal life and will not be condemned; he has crossed over from death to life.” (John 5:24) (NIV)

Christianity places a great deal of emphasis on the themes of salvation and redemption. Because Jesus Christ paid the price for our sins in our place, we are no longer under the punishment of sin.
