Problem: First Timothy 2:5 asserts that “there is one … Mediator between God and men, the Man Christ Jesus.” But Romans 8:26 informs us that the Holy Spirit intercedes for us to God “with groanings which cannot be uttered.” How can Christ be the only mediator when the Holy Spirit also mediates?
Solution: Christ is the only mediator; the Holy Spirit is only an intercessor. Christ alone died for our sins (Heb. 1:1–2), making reconciliation with God possible (2 Cor. 5:19). The Holy Spirit did not die for our sins; He prays to the Father on our behalf, based on the redeeming work of Christ. Further, the intercession of the Holy Spirit is not in heaven, as Christ’s work is (1 John 2:1–2). Rather, it is in us. The indwelling Spirit pleads in us to the Father on the grounds of the mediating work of the Son.
“Likewise the Spirit also helpeth our infirmities: for we know not what we should pray for as we ought: but the Spirit itself maketh intercession for us with groanings which cannot be uttered. (Rom 8:26)”
