Personal qualities revealed in creation. Certain facets of Jehovah’s personality are revealed by his creative works even prior to his creation of man. (Ro 1:20) The very act of creation reveals his love. This is because Jehovah is self-contained, lacking nothing. Hence, although he created hundreds of millions of spirit sons, not one could add anything to his knowledge or contribute some desirable quality of emotion or personality that He did not already possess in superior degree.​—Da 7:9, 10; Heb 12:22; Isa 40:13, 14; Ro 11:33, 34.

As the apostle Paul pointed out, Jehovah’s invisible qualities are also revealed in his material creation. (Ro 1:19, 20) His vast power is staggering to the imagination, huge galaxies of billions of stars being but ‘the work of his fingers’ (Ps 8:1, 3, 4; 19:1), and the richness of his wisdom displayed is such that, even after thousands of years of research and study, the understanding that men have of the physical creation is but “a whisper” compared with mighty thunder. (Job 26:14; Ps 92:5; Ec 3:11) Jehovah’s creative activity toward the planet Earth was marked by logical orderliness, following a definite program (Ge 1:2-31), making the earth​—as astronauts in the 20th century called it—​a jewel in space.
