According to the will of God (kata theon). See note on 2Co 7:9-11 for this phrase kata theon (according to God). The Holy Spirit is the “other Paraclete” (Joh 14:16) who pleads God’s cause with us as Christ is our Paraclete with the Father (1Jo 2:1). But more is true as here, for the Holy Spirit interprets our prayers to God and “makes intercession for us in accord with God’s will.”
