'Authority' in the Bible

The Father loves the Son and has placed all things under his authority.

and he has granted the Son authority to execute judgment, because he is the Son of Man.

If anyone wants to do God's will, he will know about my teaching, whether it is from God or whether I speak from my own authority.

The person who speaks on his own authority desires to receive honor for himself; the one who desires the honor of the one who sent him is a man of integrity, and there is no unrighteousness in him.

No one takes it away from me, but I lay it down of my own free will. I have the authority to lay it down, and I have the authority to take it back again. This commandment I received from my Father."

For I have not spoken from my own authority, but the Father himself who sent me has commanded me what I should say and what I should speak.

But when he, the Spirit of truth, comes, he will guide you into all truth. For he will not speak on his own authority, but will speak whatever he hears, and will tell you what is to come.

just as you have given him authority over all humanity, so that he may give eternal life to everyone you have given him.

So Pilate said, "Do you refuse to speak to me? Don't you know I have the authority to release you, and to crucify you?"

Jesus replied, "You would have no authority over me at all, unless it was given to you from above. Therefore the one who handed me over to you is guilty of greater sin."
