Humanity has made great advances  in harnessing the energy of the wind, the sun, the atom, and the currents. Those energies are used for good and ill!

There is one energy we have not yet mastered. Until we do, all our so-called advances will be but improved means to unimproved ends.

Paleontologist, geologist, philosopher, and Jesuit priest, Pierre Teilhard de Chardin, stated it profoundly:

What paralyzes life is lack of faith and lack of courage. The difficulty lies not in solving problems but in expressing them correctly; and we can now see that it is biologically undeniable that unless we harness passion to the service of spirit there can be no progress. Sooner or later, then, and in spite of all our incredulity, the world will take this step— because the greater truth always prevails and the greater good emerges in the end. The day will come when, after mastering the ether, the winds, the tides, gravity, we shall master the energies of love, for God. And then, for the second time in the history of the world, man will have made fire his servant.
― Pierre Teilhard de Chardin, On Love & Happiness

The real challenge is to be mastered by Love! That’s what Christians call “discipleship”!
