The Son, as the Word incarnate and the Son of Man, has the human component that made the Redemption possible. Without that, there could be no shed blood which was required for the remission of sin; and there could not be His human faith in the Father that brings us His righteousness by faith and the graces that He shares with us when we have His presence.
Without the Son’s divinity as the Word, we would not be allowed to trust Him as God and receive His Spirit. Jesus, the last Adam, became a life-giving Spirit that was made available for us at Pentecost. Both natures of Christ are essential for salvation. By His one Spirit, we have access to the Father.
Christ’s glorified humanity works for us in interesting ways that most of us are not aware of. At the right hand of the Father, Christ is our heavenly High Priest who intercedes for us. He is our one mediator between the Father and us. Without this human function, we would have no access to the Father. Because the Father abides in the Son, we also have the Spirit of the Father when we have the Spirit of His Son within us. This is why we are complete in Christ. We have the total Godhead within us when we have Christ. The Father, Word and Holy Spirit, all reside in His humanity.
Another aspect of Christ’s humanity that continues to this day is His human faith in the Father. This is how He was able to do the miracles when He was walking on earth, and His humanity is essential for us now because without it we could not have justification by faith. In Galatians 3:16, Paul says that the promises were made to Abraham and his singular seed which is Christ. The question is: How do they get to us if Christ is the singular seed? Christ shares them with us when He abides within us. This is the only way that they are available for us. They don’t come to us from a distance, and this is also how He shares His justification by faith with us which He has by His human faith in the Father.
