When the Holy Spirit is in full control of our lives, He will expect our obedience to the written Word of God. But it is part of our human problem that we would like to be full of the Spirit and yet go on and do as we please!
And I will ask the Father, and He shall give you another Paraclete, seeing He saith this of the Holy Spirit, Whom except we have, we can neither love God, nor keep His commandments?
