How might they know when they had found this great love that was to make them “a new creature”?

First of all, they might know because: 

LOVE NEVER FAILETH.

Love suffereth long and is kind; love envieth not; love vaunteth not itself; is not puffed up, does not behave unseemly; seeketh not its own; is not provoked; taketh not account of evil; rejoiceth not in unrighteousness, but rejoiceth with the truth; beareth all things; believeth all things; hopeth all things; endureth all things.

In fact, LOVE NEVER FAILETH.  Love is always a safe guide.  No matter what may be said to the contrary; no matter how much suffering it entails; no matter how seemingly fruitless the sacrifice; or how ungrateful the results, love never faileth.

How can it fail when we “seek not our own,” but only love for love’s own sake, without regard to compensation or gratitude?

St. Paul, with all who have expressed in any considerable degree this cosmic realization, seems to have expected a time, when cosmic consciousness should become so general, as to bring the kingdom of love upon earth.  This corresponds to the Millenium, which has always been prophesied, and which the present era fulfills, in all the “signs of the times” that were to usher in The Dawn.

Moreover, the idea that there shall come a time when death shall be overcome, is a persistent part of every prophecy, and of every religious cult.  In these days we find that science is speculating upon the probability of discovering a specific for senile death, as well as for the final elimination of death from disease and accidents.

Whether or not this is to be the manner of “overcoming the last enemy,” the fact remains that the almost universally held idea of physical immortality has a basis in fact, which this postulate of science symbolizes.

“For this corruptible must put on incorruption, and this mortality must put on immortality, but when this corruptible shall have put on incorruption, and this mortal shall have put on immortality, then shall come to pass the saying that is written:  ‘Death is swallowed up in victory.’”

So said St. Paul, and his words show clearly that before his time there had been a prophecy and belief in the final triumph of love over death, not as an article of faith, but as a common knowledge.

St. Paul speaks of the time when “we shall not all sleep, but we shall all be changed, in a moment, in the twinkling of an eye, at the last trump.

“And then come to the end, when he shall deliver up the kingdom to God, even the Father; when he shall have abolished all rule, all authority, and all power.”

Unquestionably, if all men on earth in the flesh and in the astral, were to come into the light of the cosmic consciousness, there would be no need for laws, for authority or power.  The kingdom, which signifies the earth as a planet, would indeed be delivered to God, which means Love, and “Love never faileth.”
