The Beloved Disciple wrote by THE SPIRIT in 1 John chapter 5:
14 Now this is the confidence that we have in Him, that if we ask anything according to His will (and nature), He hears us.
15 And if we know that He hears us, whatever we ask, we know that we have the petitions that we have asked of Him.
And Jesus spoke in John chapter 14:
12 “Most assuredly, I say to you, he who believes in Me, the works that I do he will do also; and greater works than these he will do, because I go to My Father.
13 And whatever you ask in My name (being in the same nature), that I will do, that the Father may be glorified in the Son.
14 If you ask anything in My name (according to My nature), I will do it.”
As we grow in HIS Word, we will enter into fellowship with FATHER. This will evoke a change of nature in us and thus we move toward walking fully in HIS Will. We are no longer ignorant of how we should pray for we will know HIS Will and resources available at the time of our prayer. Our words will line up with FATHER’S Word and we will not seek our own agenda but will only walk according to HIS SPIRIT and fulfill HIS Will on earth.
My friend Alan provides an interesting teaching on the needed change:
