Dr. Clarence Macartney illustrates this point by this story

Dr. Macartney claims he had a vision were he

Saw the King seated upon His throne

On either side of the throne, I saw the great angels

Uriel, Raphael, Michael, Gabriel

Before the throne stood another angel

The angel of the Book

And by his side stood one of the mortals

Who is this that you have brought, and what are his claims? Asked the King

O King, this man was a great inventor, and shed light on the pathway of man through the world

Then said the King, send him up and let him stand here by Uriel, the angel of light

So he went up

And the angel brought another man before the throne

Who is this and what are his claims?

This man was a great philosopher, who thought Thy thoughts after Thee

And the King looked at him and said

Send him up and let him stand here by the side of Raphael, the angel of Reason

So he went up and stood by Raphael

The angel brought a third mortal before the throne

Who is this and what are his claims?

This was a great patriot

With his sword he delivered his people out of the hand of tyrants

Send him up and let him stand by the side of Michael, the angel of the sword

And at forth mortal came

Who is this and what are his claims

This man sang Holy songs in praise of God

Songs which till echo through the church of the Living God

And the King said, send him up and let him stand and sing here by the side of Gabriel, the angel of Holy song

Then the angel brought another before the throne

I wondered who he was and hwy he had been brought

In him there was no greatness

In his eyes no flash of genius

The King said, who is this and what are his claims

Then the angel looked in the Book

And lifting his head said

This man won a soul for Christ

And I never heard what the King on His throne said

For all heaven rang out with a great shout

Angels and archangels, cherubim and seraphim

And all the host of the redeemed

Rejoicing over the one soul that had been redeemed

The only thing you can take to heaven with you is spiritual children
