I believe that most people do believe in God ~ in a Supreme Being, but they believe He is 'out there' somewhere ~ separate and apart from them! So they pray 'to' Him ~ NOT AS HIM! They have failed to realize (or refuse to believe) that God is the "I" within them! So they pray 'to' God hoping that He will hear and answer their prayer. And sometimes their prayers do come to pass. But God made us in His image and likeness, so that we ourselves could function AS Him! For its when 'we' 'decree a thing' with faith in the belief that God is our reality, that we shall see results! (When we realize that God is the "I" within us!) Should we, on the other hand, decree something (As the John/Jane Doe we believe ourselves to be) nothing is apt to happen! Why? Because God is a jealous God ~ He will not share His glory with another! Only when we pray in HIS name (AS HIM), can we feel confident that our prayers will manifest! When we function AS God (through faith in 'believing' that God is the "I" within us,) will we see results! It is then that we can do the things that Jesus did, and perhaps even greater things, He said!
To pray 'to' God, has little or no effect! Only as we pray AS God, will we see positive results. The Divine Mind individualized, is what a 'man' is! It 's what we are, and the 'person' we believe ourselves to be (the person our parents created when they named us) is but the illusion in which basically, the whole of humanity functions! There is ONLY God (the Father)! HE ~ is the "I" within us ~ the REALITY OF EACH OF US! Creating 'man' ~ was Gods way of creating God's! (Male and female created He them) Thus ~ children of 'men', are in reality, Gods in the infant stage of development! Only humanity is not aware of this! Thus the necessity of the Spiritual Rebirth, which can only be 'set in motion' with the realization and acknowledgement that God (the Father) is the "I" (or the "I am") within us! For there is not God AND us, there is Only God!
