What does the Bible say about the remedy for sin?

According to John 3:14-15, the remedy for sin is illustrated by the lifting up of the serpent in the wilderness, which serves as a picture of Christ being crucified. Just as the Israelites who looked upon the brazen serpent were healed, so too must we look to Jesus, who must be lifted up to atone for the sins of His people. The death of Christ was not merely an option but a necessary act to fulfill God's justice and satisfy the demands of the law. His blood atonement is the only means by which sin can be washed away, and it is through this sacrificial death that believers find the only remedy for their sins.
