What does the Bible say about substitution and deliverance?

The concept of substitution is central in Scripture, especially exemplified in Galatians 1:4, where it's stated that Christ gave Himself for our sins. This act of substitution signifies that Jesus took upon Himself the punishment for sin that rightfully belongs to us, thereby delivering those who believe from the bondage of sin and the consequences of the evil world. The biblical narrative illustrates this through various examples, such as the Passover lamb in Exodus, which served as a substitute for the children of Israel during the final plague in Egypt, illustrating the essential truth of redemption through blood.
