How can the church experience the “fellowship of the Spirit” (2 Cor. 13:14), “love of the Spirit” (Rom. 15:30), and maintain “the unity of the Spirit” (Eph. 4:3)? Without the person and presence of the Holy Spirit, it cannot be done.
To have relationship with the Father it is through the Son (1 John 2:23), to have relationship with the Son it is through the Holy Spirit (John 16:14; Rom. 8:9), and vice versa (John 14:17). Through the Spirit we experience the Son and Father.
