Time is more valuable than money, because time is irreplaceable.

We believe with all the strength of our spirit that mankind has a supreme, primary and irreplaceable need which can be satisfied only through Jesus Christ, the first-born among men, the head of the new humanity, in whom each individual reaches full self-realization.

Medical judgment can be taught - laboriously, in long periods of training - but it cannot be neatly handed over as the occasion demands it. It is the irreplaceable and untransferable contribution that the healer makes to the suffering individual who would be healed.

Do not do what someone else could do as well as you. Do not say, do not write what someone else could say, could write as well as you. Care for nothing in yourself but what you feel exists nowhere else. And, out of yourself create, impatiently or patiently, the most irreplaceable of beings.

I'm not irreplaceable ... I'm nothing but grass growing on the ground; when the grass dies, another one replaces it ...

A baby is God's opinion that life should go on. A book that does nothing to you is dead. A baby, whether it does anything to you, represents life. If a bad fire should break out in this house and I had my choice of saving the library or the babies, I would save what is alive. Never will a time come when the most marvelous recent invention is as marvelous as a newborn baby. The finest of our precision watches, the most super-colossal of our supercargo plants, don't compare with a newborn baby in the number and ingenuity of coils and springs, in the flow and change of chemical solutions, in timing devices and interrelated parts that are irreplaceable. A baby is very modern. Yet it is also the oldest of the ancients. A baby doesn't know he is a hoary and venerable antique - but he is. Before man learned how to make an alphabet, how to make a wheel, how to make a fire, he knew how to make a baby - with the great help of woman, and his God and Maker.

"Man's destiny was to conquer and rule the world, and this is what he's done - almost. He hasn't quite made it, and it looks as though this may be his undoing. The problem is that man's conquest of the world has itself devastated the world. And in spite of all the mastery we've attained, we don't have enough mastery to stop devastating the world - or to repair the devastation we've already wrought. We've poured our poisons into the world as though it were a bottomless pit - and we go on pouring our poisons into the world. We've gobbled up irreplaceable resources as though they could never run out - and we go on gobbling them up. It's hard to imagine how the world could survive another century of this abuse, but nobody's really doing anything about it. It's a problem our children will have to solve, or their children.

We think you'll find that every woman in her heart of hearts longs for three things: to be romanced, to play an irreplaceable role in a great adventure, and to unveil beauty. That's what makes a woman come alive.

Do not let your fire go out, spark by irreplaceable spark in the hopeless swamps of the not-quite, the not-yet, and the not-at-all. Do not let the hero in your soul perish in lonely frustration for the life you deserved and have never been able to reach. The world you desire can be won. It exists.. it is real.. it is possible.. it's yours.

The highest function of love is that it makes the loved one a unique and irreplaceable being.

If people destroy something replaceable made by mankind they are called vandals if they destroy something irreplaceable made by God they are called developers.
