Commentaries:
The apostle depicts a parallel between Christ's course and ours. Christ's sacrifice was substitutionary. Thus, when He was crucified, and we then accept His death for the forgiveness of our sins, it is as though we were crucified and our sins paid for in full.
However, the parallel does not end there. Sacrifice was a way of life with Jesus Christ, and it is to become our way of life. Every time we obey God's instruction as part of His purpose rather than unresistingly following the dictates of human nature, we are sacrificing ourselves to God and His purpose as a living sacrifice. Every time we sacrifice our time and energy to serve rather than merely pursue our own interests, we are following the patterns shown in the sacrifices of Leviticus and Jesus Christ's life. We are to strive to live just as He lived, and thus the daily sacrifice continues.
