Gospel Foundations: Why Was It Necessary for Christ, the Redeemer, to Die? Part 2

Since death is the punishment for sin, Christ died willingly in our place to deliver us from the power and penalty of sin and bring us back to God. By his substitutionary atoning death, he alone redeems us from hell and gains for us forgiveness of sin, righteousness, and everlasting life.

For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God. Substitutionary Atonement.
