"With all prayer and supplication praying at all seasons in the Spirit, and watching thereunto in all perseverance and supplication for all the saints."--EPH. vi. 18. "Praying in the Holy Spirit."--JUDE 20. The Holy Spirit has been given to every child of God to be his life. He dwells in him, not as a separate Being in one part of his nature, but as his very life. He is the Divine power or energy by which his life is maintained and strengthened. All that a believer is called to be or to do, the Holy Spirit can and will work in him. If he does not know or yield to the Holy Guest, the Blessed Spirit cannot work, and his life is a sickly one, full of failure and of sin. As he yields, and waits, and obeys the leading of the Spirit, God works in him all that is pleasing in His sight. This Holy Spirit is, in the first place, a Spirit of prayer. He was promised as a "Spirit of grace and supplication," the grace for supplication. He was sent forth into our hearts as "the Spirit of adoption, whereby we cry, Abba, Father." He enables us to say, in true faith and growing apprehension of its meaning, Our Father which art in heaven. "He maketh intercession for the saints according to God." And as we pray in the Spirit, our worship is as God seeks it to be, "in spirit and in truth." Prayer is just the breathing of the Spirit in us; power in prayer comes from the power of the Spirit in us, waited on and trusted in. Failure in prayer comes from feebleness of the Spirit's work in us. Our prayer is the index of the measure of the Spirit's work in us. To pray aright, the life of the Spirit must be right in us. For praying the effectual, much-availing prayer of the righteous man everything depends on being full of the Spirit.
