"Because the human life and work of Jesus was in entire agreement with the life and work of the Father, the human activity of Jesus exhibited a perfect parallelism to the saving activity of God himself, but more than that, his activity on earth was itself the saving activity of God at work among men and women." (Thomas F. Torrance)
In other words, because Jesus lived His life in alignment with the will of His Father, He manifested the saving activity of God through His life and work. There is something incredibly powerful about a life that is lived in alignment with its purpose!
I can't help to wonder what the impact would be on our world if those who bear the name of Christ, that is Christians, were to live their lives "in entire agreement with the life and work of the Father." Imagine if Christ followers were to "[exhibit] a perfect parallelism to the saving activity of God." What would the Church look like if its "activity on earth was itself the saving activity of God at work among men and women?"
Maybe we would see the same power and presence of the Holy Spirit seen in the Acts 2 church in the 21st century Church as "the Lord [adds] to [our] number daily those who [are] being saved." (Acts 2:47)
