There are three very simple lessons that the believer, who would enjoy the blessing of being taught to pray by the Spirit of prayer, must know. The first is: _Believe that the Spirit dwells in you_ (Eph. i. 13). Deep in the inmost recesses of his being, hidden and unfelt, every child of God has the Holy, Mighty Spirit of God dwelling in him. He knows it by faith, the faith that, accepting God's word, realises that of which he sees as yet no sign. "We receive the promise of the Spirit by faith." As long as we measure our power, for praying aright and perseveringly, by what we feel, or think we can accomplish, we shall be discouraged when we hear of how much we ought to pray. But when we quietly believe that, in the midst of all our conscious weakness, the Holy Spirit as a Spirit of supplication is dwelling within us, _for the very purpose of enabling us to pray in such manner and measure as God would have us_, our hearts will be filled with hope. We shall be strengthened in the assurance which lies at the very root of a happy and fruitful Christian life, that _God has made an abundant provision for our being what He wants us to be_. We shall begin to lose our sense of burden and fear and discouragement about our ever praying sufficiently, because we see that the Holy Spirit Himself will pray, is praying, in us. The second lesson is: _Beware above everything of grieving the Holy Spirit_ (Eph. iv. 30). If you do, how can He work in you the quiet, trustful, and blessed sense of that union with Christ which makes your prayers well pleasing to the Father? Beware of grieving Him by sin, by unbelief, by selfishness, by unfaithfulness to His voice in conscience. Do not think grieving Him a necessity: that cuts away the very sinews of your strength. Do not consider it impossible to obey the command, "Grieve not the Holy Spirit." He Himself is the very power of God to make you obedient. The sin that comes up in you against your will, the tendency to sloth, or pride, or self-will, or passion that rises in the flesh, your will can, in the power of the Spirit, at once reject, and cast upon Christ and His blood, and your communion with God is immediately restored. Accept each day the Holy Spirit as your Leader and Life and Strength; you can count upon Him to do in your heart all that ought to be done there. He, the Unseen and Unfelt One, but known by faith, gives there, unseen and unfelt, the love and the faith and the power of obedience you need, because He reveals Christ unseen within you, as actually your Life and Strength. Grieve not the Holy Spirit by distrusting Him, because you do not feel His presence in you.
