what authority does the average christian today have?

I have no idea what authority the "average christian" has today. You see I'm special.

1 Peter, Chapter 2, verse 9:

But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light:

i say "NO" to "that is the best we can do " .scripture is always true. i wont say no to that.

the Spirit (God) is the authority, and to rightly divide and interpret Scripture (the Spirit). experience through following God and seeking truth over error in any and all misunderstandings in part and half truths can lead to more and more wholeness in thought as befits a follower of Christ. not of any of our own ideas made into idols as it were, even to whatever degree we might at times past and or present, still.... as was/is needful at that and each level (milk, herbs, meat, ect) of understanding as the Spirit was/is able to use to help each of us -- at that/each level as much as it could, in various different ways that it reaches each person (where they are at in life + who they are) and at various times and seasons of a disiple of the Spirit/Christ.... but with seeking God and truth more and more in our lives over time.... we hopefully learn more and more to think on things much more correctly and holistically. not from one point of view or another or yet another; but instead finding more and more the straight path of truth.

being a person often in authority, I do not see how that relates.

thanks all

they have what they use.

It depends on what faith they carry and who actually has the authority

“And Jesus answering saith unto them, Have faith in God. For verily I say unto you, That whosoever shall say unto this mountain, Be thou removed, and be thou cast into the sea; and shall not doubt in his heart, but shall believe that those things which he saith shall come to pass; he shall have whatsoever he saith.

Therefore I say unto you, What things soever ye desire, when ye pray, believe that ye receive them, and ye shall have them.

And when ye stand praying, forgive, if ye have ought against any: that your Father also which is in heaven may forgive you your trespasses.

But if ye do not forgive, neither will your Father which is in heaven forgive your trespasses.”
‭‭Mark‬ ‭11:22-26‬ ‭KJV‬‬

his authority is given to us by faith who receive his word of faith it only operates within his word and comes from his word because the authority is all his

The authority is with him , who is with us

“And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth. Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:

Teaching them to observe all things whatsoever I have commanded you:

and, lo, I am with you alway, even unto the end of the world. Amen.”
‭‭Matthew‬ ‭28:18-20‬ ‭

“Even the mystery which hath been hid from ages and from generations, but now is made manifest to his saints: To whom God would make known what is the riches of the glory of this mystery among the Gentiles; which is Christ in you, the hope of glory:”
‭‭Colossians‬ ‭1:26-27‬ ‭

we don’t have authority we have the author living in us and he has all the authority so we then are baptized into his name who believe

Personally I believe there's too much emphasis on a Christian's "authority," and not enough on our submission to God. Our power doesn't come from claiming authority over devils or the Devil; it comes from our being in Christ and dead to our old self and to the world.

When I hear preachers talking about the believer's "authority," it's usually followed with: By claiming your authority you can walk in "victory"—whatever that means. Usually it means you can accomplish something great for God like: get that dream job, land the perfect spouse, make a pile of money or have perfect health.

So in answer to your question, my opinion is it's futile to concern ourselves with our "authority"; we should think more in terms of His authority. If we're doing His will, then there will be nothing to worry about.

The notion of the ONLY true God seemed to be the running theme in my most recent studies, where it stands out often contrary to the most common (in?)look. For example, Jude's mention of 'hating the garments stained by the flesh' spoke in regard to care for my own garment before worry about the mustard stain on yours, not that I shouldn't address your mustard stain as much as this is the approach in making sure I (still) haven't got, or at least remembering that I did before it was laundered, a ketchup stain before I do say anything at all.

Although the OP and some subsequent commentators may be alluding to an elite force of Christians (of which I suspect might be excluded from), in this case, I especially noted the Luke 10:20 prooftext (b), "but rejoice that your names are written in heaven."

The gospel text were said to the apostles who were his disciples at that time. I agree that Jesus has all authority. I do not see it being passed onto those he is in.

I’m leaving

I do not see how authority comes form "our being in Christ and dead to our old self and to the world. "

I’ll be free when I do leave

That authority was given to the apostles, not us. "
And over all the power of the enemy (κα επ πασαν την δυναμιν του εχθρου). This is the heart of "the authority" (την εξουσιαν) here given by Jesus which is far beyond their expectations. The victory over demons was one phase of it. The power to tread upon serpents is repeated in Mark 16:18 (NAS)

Nothing shall in any wise hurt you (ουδεν υμας ου μη αδικησε). Text has future active indicative, while some MSS. read αδικηση, aorist active subjunctive of αδικεω, common verb from αδικος (α privative and δικος), to suffer wrong, to do wrong. The triple negative here is very strong. Certainly Jesus does not mean this promise to create presumption or foolhardiness for he repelled the enemy's suggestion on the pinnacle of the temple."

yes it’s the receiving of Jesus I rookie hearts that brings the “authority of faith “ which he brings with him faith is something special it’s simplicity

“And God said, Let there be light: and there was light.”
‭‭Genesis‬ ‭1:3‬ ‭KJV‬‬

Gods word is true when he speaks it it’s a matter of if we will believe it and move
like this faith is built from Gods words and look at its creative power to achieve what he said

This is what the obedience of faith has the power to achieve

“And the Lord said unto Moses, Stretch out thine hand toward heaven, that there may be darkness over the land of Egypt, even darkness which may be felt.

And Moses stretched forth his hand toward heaven; and there was a thick darkness in all the land of Egypt three days:”
‭‭Exodus‬ ‭10:21-22‬ ‭KJV‬‬

Jesus words have the same authority

“And he arose, and rebuked the wind, and said unto the sea, Peace, be still. And the wind ceased, and there was a great calm. And he said unto them, Why are ye so fearful? how is it that ye have no faith? And they feared exceedingly, and said one to another, What manner of man is this, that even the wind and the sea obey him?”
‭‭Mark‬ ‭4:39-41‬ ‭KJV‬‬

see how Jesus is asking then why they have no faith ? It’s faith that we need
And we find it in the gospel

“For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth; to the Jew first, and also to the Greek.

For therein is the righteousness of God revealed from faith to faith: as it is written, The just shall live by faith.”
‭‭Romans‬ ‭1:16-17‬ ‭KJV‬‬

Faith is why Peter walked in water and also why he called out for Jesus when he Sank. It’s why the sinful woman came running and weeping at her lords feet , it’s why Jesus can say with the same word and power of faith to believers

“For the Father judgeth no man, but hath committed all judgment unto the Son:

Verily, verily, I say unto you, He that heareth my word, and believeth on him that sent me, hath everlasting life, and shall not come into condemnation; but is passed from death unto life.

For as the Father hath life in himself; so hath he given to the Son to have life in himself; And hath given him authority to execute judgment also, because he is the Son of man.”
‭‭John‬ ‭5:22, 24, 26-27‬ ‭

even death must obey the lords word

“And when he thus had spoken, he cried with a loud voice, Lazarus, come forth. And he that was dead came forth, bound hand and foot with graveclothes: and his face was bound about with a napkin. Jesus saith unto them, Loose him, and let him go.”
‭‭John‬ ‭11:43-44‬ ‭KJV‬‬

amen indeed he is the authority and we can receive him into our heart to shepherd us through the world into his eternal kingdom

“For ye were as sheep going astray; but are now returned unto the Shepherd and Bishop of your souls.”
‭‭1 Peter‬ ‭2:25‬ ‭KJV‬‬

faith is where authority lives when we know he is with us there is faith found
