Loyalty, like grace, shows the nobility of the giver of it more than the nobility of the receiver

Though loyalty, well held, to fools does make

Our faith mere folly; yet he that can endure

To follow with allegiance a fall'n lord,

Does conquer him that did his master conquer.

-- William Shakespeare, Antony and Cleopatra, Act III, Scene XIII

For loyalty is still the same,

Whether it win or lose the game;

True as the dial to the sun,

Although it be not shone upon.

-- Samuel Butler, Hudibras

I have coveted no man's silver, or gold, or apparel. Yea, ye yourselves know, that these hands have ministered unto my necessities, and to them that were with me. I have shewed you all things, how that so labouring ye ought to support the weak, and to remember the words of the Lord Jesus, how he said, It is more blessed to give than to receive.

-- Acts 20:33ff.

Paul's chutzpah: Chief of sinners says "I am pure from the blood of all men"

Wherefore I take you to record this day, that I am pure from the blood of all men.

-- Acts 20:26

And Saul was consenting unto his death. 

-- Acts 8:1

And when the blood of thy martyr Stephen was shed, I also was standing by, and consenting unto his death, and kept the raiment of them that slew him.

-- Acts 22:20

Christ Jesus came into the world to save sinners; of whom I am chief.

-- 1 Timothy 1:15

You'll be happier giving than receiving

"It is more blessed to give than to receive"

-- Acts 20:35

My words shall not pass away?

"My words shall not pass away" (Mt. 24:35, Mk. 13:31, Lk. 21:33).

"In all things I [Paul] have shown you that by so toiling one must help the weak, remembering the words of the Lord Jesus, how he said, 'It is more blessed to give than to receive'" (Acts 20:35).

-----------------------------------------

The words of Jesus Paul quotes are unexampled in the Gospels.

Isn't it just a little odd that were it not for Paul "it is more blessed to give than to receive" would have passed away, even though "... the Counselor, the Holy Spirit, whom the Father will send in my name, he will teach you all things, and bring to your remembrance all that I have said to you" (John 14:25). Obviously not to the authors of the Gospels.

There must be other sayings we do not know about. After all, not all his deeds have been recorded, either:

"And there are also many other things which Jesus did, the which, if they should be written every one, I suppose that even the world itself could not contain the books that should be written. Amen" (John 21:25).
