Why many pray and only a few receive answers?

 And this is the confidence that we have in him, that, if we ask any thing according to his will, he heareth us:1 John 5:14 

Why do many pray and only a few receive from Him? All prayers you pray often are spiritual communication you have with the Father, God. Communicating with God requires a means which is faith, without faith you can’t communicate with Him. The means by which you call your earthly father and loved ones all around the world is through a telephone call. When you make a telephone call you hear a voice which gives you confidence that the receiver heard your request, this is not different from a child of God who uses faith as a communicating means to request from the father, through faith He/She believes God has heard and has spoken. 1 John 5:13-14 ‘These things have I written unto you that believe on the name of the Son of God; that ye may know that ye have eternal life, and that ye may believe on the name of the Son of God. And this is the confidence that we have in him, that, if we ask any thing according to his will, he heareth us:’

If a Believer lack this spiritual means of communicating with the father, He will keep praying without receiving anything from above.
Dear reader I hope you have been blessed today, take your faith as a means by which you can communicate with the Father and have this confidence that He heard you.

Conclusion:

Your faith is your spiritual telephone by which you communicate with the father, and your confidence in Him gives you assurance that He heard you.
