The Kingdom of the Lord Jesus Christ responds to the prayers of His belivers when they operate in His faith. When we come to pray we must approach our heavenly Father in a posture of belief, trust, and faith. Doubt, fear, and unbelief hinder our prayer lives and negate or diminish or desired outcomes. Our prayers are to be founded on the Word of God. Our prayers must please God, and without faith it is impossible to please Him. 

Philippians 4:6 King James Version (KJV)

6 Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God.
