Romans 8:27

He that searcheth (o eraunwn). God ( 1 Samuel 16:7 ). According to the will of God (kata qeon). See 2 Corinthians 7:9-11 for this phrase kata qeon (according to God). The Holy Spirit is the "other Paraclete" ( John 14:16 ) who pleads God's cause with us as Christ is our Paraclete with the Father ( 1 John 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."
