How do we know Christ bore the sins of His people?

The truth that Christ bore the sins of His people is explicitly stated in 1 Peter 2:24: 'Who his own self bare our sins in his body on the tree, that we, being dead to sins, should live unto righteousness.' This affirms that it was through His suffering and sacrifice that believers find salvation and justification before God. Moreover, the discourse emphasizes that this was the work of the Father and Son, a complete divine initiative where man contributed nothing but sin. Therefore, our faith rests in the finished work of Christ.
