We have sought more than once to enforce the truth, that while we ordinarily seek the reasons of our prayers not being heard in the thing we ask not being according to the will of God, Scripture warns us to find the cause in ourselves, in our not being in the right state or not asking in the right spirit.  The thing may be in full accordance with His will, but the asking, the spirit of the supplicant, not; then we are not heard.  As the great root of all sin is self and self-seeking, so there is nothing that even in our more spiritual desires so effectually hinders God in answering as this:  we pray for our own pleasure or glory.  Prayer to have power and prevail must ask for the glory of God; and he can only do this as he is living for God's glory.

In George Muller we have one of the most remarkable instances on record of God's Holy Spirit leading a man deliberately and systematically, at the outset of a course of prayer, to make the glorifying of God his first and only object.  Let us ponder well what he says, and learn the lesson God would teach us through him:--

`I had constantly cases brought before me, which proved that one of the especial things which the children of God needed in our day, was to have their faith strengthened.

`I longed, therefore, to have something to point my brethren to, as a visible proof that our God and Father is the same faithful God as ever He was; as willing as ever to PROVE Himself to be the LIVING GOD in our day as formerly, to all who put their trust in Him.

`My spirit longed to be instrumental in strengthening their faith, by giving them not only instances from the word of God, of His willingness and ability to help all who rely upon Him, but to show them by proofs that He is the same in our day.  I knew that the word of God ought to be enough, and it was by grace enough for me; but still I considered I ought to lend a helping hand to my brethren.

`I therefore judged myself bound to be the servant of the Church of Christ, in the particular point in which I had obtained mercy; namely, in being able to take God at His word and rely upon it.  The first object of the work was, and is still:  that God might be magnified by the fact that the orphans under my care are provided with all they need, only by prayer and faith, without any one being asked; thereby it may be seen that God is FAITHFUL STILL, AND HEARS PRAYER STILL.

`I have again these last days prayed much about the Orphan House, and have frequently examined my heart; that if it were at all my desire to establish it for the sake of gratifying myself, I might find it out.  For as I desire only the Lord's glory, I shall be glad to be instructed by the instrumentality of my brother, if the matter be not of Him.

`When I began the Orphan work in 1835, my chief object was the glory of God, by giving a practical demonstration as to what could be accomplished simply through the instrumentality of prayer and faith, in order thus to benefit the Church at large, and to lead a careless world to see the reality of the things of God, by showing them in this work, that the living God is still, as 4000 years ago, the living God.  This my aim has been abundantly honoured.  Multitudes of sinners have been thus converted, multitudes of the children of God in all parts of the world have been benefited by this work, even as I had anticipated.  But the larger the work as grown, the greater has been the blessing, bestowed in the very way in which I looked for blessing:  for the attention of hundreds of thousands has been drawn to the work; and many tens of thousands have come to see it.  All this leads me to desire further and further to labour on in this way, in order to bring yet greater glory to the Name of the Lord.  That He may be looked at, magnified, admired, trusted in, relied on at all times, is my aim in this service; and so particularly in this intended enlargement.  That it may be seen how much one poor man, simply by trusting in God, can bring about by prayer; and that thus other children of God may be led to carry on the work of God in dependence upon Him; and that children of God may be led increasingly to trust in Him in their individual positions and circumstances, therefore I am led to this further enlargement.'
