Using the name of Jesus and having a revelation of the power implicit in Him are two different things,even the mere teaching of the power that is in his name is not enough.
No one alone gets this revelation, this alone can be given by the Holy Spirit.
John 16:13 Amplified Bible (AMP)
13 But when He, the Spirit of Truth, comes, He will guide you into all the truth [full and complete truth]. For He will not speak on His own initiative, but He will speak whatever He hears [from the Father—the message regarding the Son], and He will disclose to you what is to come [in the future].
It is the Holy Spirit who reveals to us the truth contained in his powerful name,the word of God reveals to us that we are saved in his name, we receive baptism also in his name ,the sick are healed by that glorious name and demons are fleeing almighty name.
In the book of facts we can see how powerfully our brothers used the name of Jesus I remember that in chapter 3:1-6 Peter with John entered the temple there was a man begging for alms, he was lame from birth, they just told him to look at us in the name of Jesus get up and walk, what a precious revelation there is in the book of Acts.
When we pray in his precious name we present to the Father all that Jesus has done for us this is a wonderful truth as if he himself were praying as if he were asking ,John 16:24
24 Until now you have not asked [the Father] for anything in My name; but now ask and keep on asking and you will receive, so that your joy may be full and complete.
Every believer has a legal right to use the name of Jesus as a result of his or her new birth, but to use it with power depends on genuine communion with Him Father and a life of holiness in this lies the revelation of his name that :
1 John 2:6
6 whoever says he lives in Christ [that is, whoever says he has accepted Him as God and Savior] ought [as a moral obligation] to walk and conduct himself just as He walked and conducted Himself.
