If you want to see His power manifested to meet any need in any situation you must speak In His Name - the name of the One who holds all power Rom 13:1 .   

At that time the Lord separated the tribe of Levi, to bear the ark of the covenant of the Lord, to stand before the Lord to minister unto him, and to bless in his name, unto this day. Deu 10:8

The sons of Amram; Aaron and Moses: and Aaron was separated, that he should sanctify the most holy things, he and his sons for ever, to burn incense before the Lord, to minister unto him, and to bless in his name for ever. 1Ch 23:13

Then I said, I will not make mention of him, nor speak any more in his name.     But his word was in my heart as a burning fire shut up in my bones, and I was weary with forbearing, and I could not stay. Jer 20:9

And I will strengthen them in the Lord; and they shall walk up and down in his name, says the Lord. Zec 10:12 By His Word and in His Spirit we will accomplish great things.

And in his name shall the Gentiles trust. Mat 12:21 At the time of Jesus` ministry this had not yet been fulfilled.

And that repentance and remission of sins should be preached in his name among all nations, beginning at Jerusalem. Luk 24:47 Repentance is a result of faith in Jesus which enables appropriation of remission resulting in the New Birth which places us In Christ.      But reconciliation with God comes only by acknowledging that Jesus Is God who in His own body has paid for all the benefits of Grace.      By speaking In His Name the Holy Spirit Of Christ effects that which is spoken,

Now when he was in Jerusalem at the passover, in the feast day, many believed in his name, when they saw the miracles which he did. Joh 2:23 Miracles engender faith.     Signs are for unbelievers.      They believed In His Name.     They believed that Jesus is Messiah, Immanuel, Mighty God.

And his name through faith in his name has made this man strong, whom you see and know: yes, the faith which is by him has given him this perfect soundness in the presence of you all. Act 3:16 Faith in the Name Of Jesus brought about this miracle.

The following is from In My Father`s Name     ⇒
Why would Jesus talk about His Father's name without saying what it is?     

If you think that the Father's name is YHVH you are identifying the Father as a separate person from Jesus.     You have two people: YHVH and Jesus.     

The Father of Jesus is His Holy Spirit Mat 1:18,20.     

The Father is not a separate person from Jesus Joh 10:30.     

Hence, the name of the Father is Jesus.     Jesus instructed us to talk to His Holy Spirit Father In My Name - calling Him by the name, Jesus.     

I am come in my Father`s name, and you receive me not: if another shall come in his own name, him you will receive. Joh 5:43 What is the Father's name which Jesus came in?       Jesus.        Jesus is the incarnation of His Holy Spirit Father.        This, as usual, is the Holy Spirit speaking through Jesus.       However, in this verse He very plainly speaks to the fact that His Holy Spirit has come to manifest Himself to the world, and His name is Jesus.        Jesus is the Father revealing Himself to us directly.        Jesus is the Truth.        All others come in their own name speculating about and talking about deity, Who is the one they will receive that comes in his own name?       The Beast of Revelation - the Anti Christ.

Jesus answered them, I told you, and you believed not: the works that I do in my Father`s name, they bear witness of me. Joh 10:25 What is Jesus' Father's name?       Jesus.        Remember, the Father of Jesus is His Holy Spirit Mat 1:18,20 It was as if they had a recorder with them this time - so they could gather evidence against Him.        He basically is saying    ➛ I am the Messiah    ➛ the works I do are proof
