“The sacrifices of God are a broken spirit; a broken and contrite heart, O God, Thou wilt not despise” (PSM 51:17). Brokenness is the means by which God conveys maturity and develops character. His discipline in the lives of believers brings each into abandonment of self to God in an attitude of prevailing prayer.
From the autobiography of George Mueller
Dependence – Absolute trust in the merits of Christ as our grounds for blessing & our oneness with Him.
Separation – Abandonment of all known sin.
Belief – Faith in the complete veracity of God’s character. He is and is the rewarder of those who diligently
seek Him.
Motive – Ask according to His will; for our good and His glory.
Perseverance – Patient waiting on Him
Where these conditions are not met God’s answer would both dishonor His character and damage the suppliant.
