St. Paul tells that in light of God’s mercy we are to be living sacrifices with our whole bodies. The difficulty with this is the a sacrifice that still lives can get up and move away from its calling. Thus, through that very mercy we to continually sacrifice ourselves in order to be raised into new life in Christ. It’s not easy, but it is what God has called us to in Christ Jesus and thus he will empower us to do so.
