who his own self bore our sins in his body on the tree, that we, having died to sins, might live to righteousness; by whose stripes you were healed.
bore our sins -- To bear sins was to be punished for them (cf. Numbers 14:33; Ezekiel 18:20). Christ bore the punishment and the penalty for believers, thus satisfying a holy God (3:18; see notes on 2 Corinthians 5:21; Galatians 3:13). This great doctrine of the substitutionary atonement is the heart of the gospel. - MSB
