After locating the will of God concerning your situation, the next thing to be done is to build up faith for effectual communication. Faith is a potent force without which prayer will be absolutely unproductive. The Bible calls faith “The substance of things hoped for…”(Hebrews 11:1). That means it is the ticket on which you take delivery of anything from heaven.
Read Matthew 17:19-20 from your Bible
Until faith is in place, prayer will only end up in frustration. As powerful as the Word of God is, it can only produce when faith is present.
Read Hebrews 4:2 from your Bible
Every conflict in life is a direct attack from the forces of darkness and the Word of God is the light that shatters darkness (John 1:5). Psalm 119:130 tells us that it is the entrance of the Word that gives light. Until the Word gains entrance into the heart and generates faith, it does not become light; and until it becomes light, it cannot shatter darkness.
You don’t pray for faith, you cultivate it by staying with the Word until the assurance of its reality is established in your heart.
“So then faith cometh by hearing, and hearing by the word of God.”(Romans 10:17).
Once faith is established, you can be sure of results when you pray (James 1:6-7).
Many have been following Jesus for long. They have done all manner of things in the name of prayer, including 21 days self-inflicted fast; whereas all that God is waiting to see in them is a believing heart.
Read Hebrews 11:6 from your Bible
So, it is you, not God, who determines whether your prayer gets answered or not. As for God, His side is settled. He is constant, man is the variable.
His Word says, “No good thing will He withhold from them that walk uprightly”(Psalm 84:11). Whatsoever makes for your welfare and that of His kingdom is good in His sight, so He will not withhold it from you as long as you ask in faith.
