Hi Julie,
Yes Graham Cooke is a great teacher and you would enjoy reading and learning from him. And as you stay close to Beloved Jesus, you will hear His voice, and not listen to the voice of strangers, as Jesus said. Yes psychics and others do hear voices too from the dark realm, but as you know the devil is a counterfeit, a liar and a deceiver. He will copy what our good Father has given to us. And now that you belong to Jesus you can keep close to Him and hear His voice. The secular world doesn't understand all of this. but Jesus does, and Holy Spirit will guide you.
" Most assuredly I say to you, he who does not enter the sheepfold by the door, but climbs in some other way, the same is a thief and a robber. But he who enters by the door is the shepherd of the sheep. To him the doorkeeper opens and the sheep hear his voice and he calls his own sheep by name and leads them out. And when he brings out his own sheep, he goes before them and the sheep follow him, for they know his voice. Yet they will by no means follow a stranger, but will flee from him, for they do not know the voice of strangers." John 10:1-5.
Graham Cooke can probably give you better teaching than I can, but from these verses it seems that Jesus is saying that we who are His sheep, will know his voice. We may hear the voice of strangers, but will not listen to or follow them, Don't you love what Jesus says, that he calls us by NAME, He knows your name Julie! You are special to Him..
So bless you Julie is your walk with Beloved Jesus, as you stay close in His presence, just as Elisha listened to God and heard so clearly from Him.
With love and blessings,
