God manifests Himself also in the preservation of created beings. We see that the achievements of men are realised by using materials created by God; and, with time and use, these wear out, deteriorate and disappear.
How different is the destiny of the works which originate solely from the hand of God! Consider the sun: it has always the same strength, the same degree of heat, the same brilliance, follows always the same course laid out for it by God! The same is true of the moon, the stars, the planets, the earth, the seas and all that exists and was created by God!
It all must remain the same because that is what God wishes, since that depends on his omnipotent will. And they are here, before our eyes, indisputable witnesses to the power, the wisdom, the will and the eternal existence of God.
God created, for the good of humanity, many invisible forces, whose existence nobody doubts. Who, for instance, has seen the wind? We hear it, we feel it when it blows upon us, and we see its effects when it shakes the trees and tosses the seas. The same is true of oxygen, hydrogen, electricity, etc.
The person who believes in God is happy, because he knows he has a Father from whom all things come, yet is above all human paternity. He loves his Father, rests in his arms and lives for this Father who is goodness, mercy, forgiveness and love!”
